>gnl|CDD|232920 TIGR00326, eubact_ribD, riboflavin biosynthesis protein RibD.  This
           model describes the ribD protein as found in Escherichia
           coli. The N-terminal domain includes the conserved
           zinc-binding site region captured in the model
           dCMP_cyt_deam and shared by proteins such as cytosine
           deaminase, mammalian apolipoprotein B mRNA editing
           protein, blasticidin-S deaminase, and Bacillus subtilis
           competence protein comEB. The C-terminal domain is
           homologous to the full length of yeast HTP reductase, a
           protein required for riboflavin biosynthesis. A number
           of archaeal proteins believed related to riboflavin
           biosynthesis contain only this C-terminal domain and are
           not found as full-length matches to this model
           [Biosynthesis of cofactors, prosthetic groups, and

>gnl|CDD|238612 cd01285, nucleoside_deaminase, Nucleoside deaminases include
           adenosine, guanine and cytosine deaminases. These
           enzymes are Zn dependent and catalyze the deamination of
           nucleosides. The zinc ion in the active site plays a
           central role in the proposed catalytic mechanism,
           activating a water molecule to form a hydroxide ion that
           performs a nucleophilic attack on the substrate. The
           functional enzyme is a homodimer. Cytosine deaminase
           catalyzes the deamination of cytosine to uracil and
           ammonia and is a member of the pyrimidine salvage
           pathway. Cytosine deaminase is found in bacteria and
           fungi but is not present in mammals; for this reason,
           the enzyme is currently of interest for antimicrobial
           drug design and gene therapy applications against
           tumors. Some members of this family are tRNA-specific
           adenosine deaminases that generate inosine at the first
           position of their anticodon (position 34) of specific
           tRNAs; this modification is thought to enlarge the codon
           recognition capacity during protein synthesis. Other
           members of the family are guanine deaminases which
           deaminate guanine to xanthine as part of the utilization
           of guanine as a nitrogen source.

          hydrogen peroxide, alkyl hydroperoxides and
          peroxynitrite. As with all other PRXs, the N-terminal
          peroxidatic cysteine of PRX5 is oxidized into a
          sulfenic acid intermediate upon reaction with
          peroxides. Human PRX5 is able to resolve this
          intermediate by forming an intramolecular disulfide
          bond with its C-terminal cysteine (the resolving
          cysteine), which can then be reduced by TRX, just like
          an atypical 2-cys PRX. This resolving cysteine,
          however, is not conserved in other members of the
          subfamily. In such cases, it is assumed that the
          oxidized cysteine is directly resolved by an external
          small-molecule or protein reductant, typical of a 1-cys
          PRX. In the case of the H. influenza PRX5 hybrid, the
          resolving glutaredoxin domain is on the same protein
          chain as PRX. PRX5 homodimers show an A-type interface,
          similar to atypical 2-cys PRXs.

>gnl|CDD|143557 cd07448, CRD_FZ4, Cysteine-rich Wnt-binding domain of the frizzled
           4 (Fz4) receptor.  The cysteine-rich domain (CRD) is an
           essential extracellular portion of the frizzled 4 (Fz4)
           receptor, and is required for binding Wnt proteins,
           which play fundamental roles in many aspects of early
           development, such as cell and tissue polarity, neural
           synapse formation, and the regulation of proliferation.
           Fz proteins serve as Wnt receptors for multiple signal
           transduction pathways, including  both beta-catenin
           dependent and -independent cellular signaling, as well
           as the planar cell polarity pathway and the Ca(2+)
           modulating signaling pathway. CRD containing Fzs have
           been found in diverse species from amoebas to mammals.
           10 different frizzled proteins are found in vertebrata.
           Frizzled 4 (Fz4) activates the
           Ca(2+)/calmodulin-dependent protein kinase II and
           protein kinase C of the Wnt/Ca(2+) signaling pathway
           during retinal angiogenesis. Mutations in Fz4 lead to
           familial exudative vitreoretinopathy (FEVR), a
           hereditary ocular disorder characterized by failure of
           the peripheral retinal vascularization. In addition, the
           interplay between Fz4 and norrin as a receptor-ligand
           pair plays an important role in vascular development in
           the retina and inner ear in a Wnt-independent manner.

>gnl|CDD|197200 cd00138, PLDc_SF, Catalytic domain of phospholipase D superfamily
          proteins.  Catalytic domain of phospholipase D (PLD)
          superfamily proteins. The PLD superfamily is composed
          of a large and diverse group of proteins including
          plant, mammalian and bacterial PLDs, bacterial
          cardiolipin (CL) synthases, bacterial
          phosphatidylserine synthases (PSS), eukaryotic
          phosphatidylglycerophosphate (PGP) synthase, eukaryotic
          tyrosyl-DNA phosphodiesterase 1 (Tdp1), and some
          bacterial endonucleases (Nuc and BfiI), among others.
          PLD enzymes hydrolyze phospholipid phosphodiester bonds
          to yield phosphatidic acid and a free polar head group.
          They can also catalyze the transphosphatidylation of
          phospholipids to acceptor alcohols. The majority of
          members in this superfamily contain a short conserved
          sequence motif (H-x-K-x(4)-D, where x represents any
          amino acid residue), called the HKD signature motif.
          There are varying expanded forms of this motif in
          different family members. Some members contain variant
          HKD motifs. Most PLD enzymes are monomeric proteins
          with two HKD motif-containing domains. Two HKD motifs
          from two domains form a single active site. Some PLD
          enzymes have only one copy of the HKD motif per subunit
          but form a functionally active dimer, which has a
          single active site at the dimer interface containing
          the two HKD motifs from both subunits. Different PLD
          enzymes may have evolved through domain fusion of a
          common catalytic core with separate substrate
          recognition domains. Despite their various catalytic
          functions and a very broad range of substrate
          specificities, the diverse group of PLD enzymes can
          bind to a phosphodiester moiety. Most of them are
          active as bi-lobed monomers or dimers, and may possess
          similar core structures for catalytic activity. They
          are generally thought to utilize a common two-step
          ping-pong catalytic mechanism, involving an
          enzyme-substrate intermediate, to cleave phosphodiester
          bonds. The two histidine residues from the two HKD
          motifs play key roles in the catalysis. Upon substrate
          binding, a histidine from one HKD motif could function
          as the nucleophile, attacking the phosphodiester bond
          to create a covalent phosphohistidine intermediate,
          while the other histidine residue from the second HKD
          motif could serve as a general acid, stabilizing the
          leaving group.
