>gnl|CDD|187704 cd09280, RNase_HI_eukaryote_like, Eukaryotic RNase H is longer and
           more complex than their prokaryotic counterparts  and
           unlike prokaryote, RNase H are essential in higher
           eukaryote.  Ribonuclease H (RNase H) is classified into
           two families, type 1 (prokaryotic RNase HI, eukaryotic
           RNase H1 and viral RNase H) and type 2 (prokaryotic
           RNase HII and HIII, and eukaryotic RNase H2). RNase H is
           an endonuclease that cleaves the RNA strand of an
           RNA/DNA hybrid in a sequence non-specific manner. RNase
           H is involved in DNA replication, repair and
           transcription. One of the important functions of RNase H
           is to remove Okazaki fragments during DNA replication.
           RNase H is widely present in various organisms,
           including bacteria, archaea and eukaryote and most
           prokaryotic and eukaryotic genomes contain multiple
           RNase H genes. Despite the lack of amino acid sequence
           homology, Type 1 and type 2 RNase H share a main-chain
           fold and steric configurations of the four acidic
           active-site (DEDD)  residues and have the same catalytic
           mechanism and functions in cells.  Eukaryotic RNase H is
           longer and more complex than in prokaryotes. Almost all
           eukaryotic RNase HI have highly conserved regions at the
           N-terminal called hybrid binding domain (HBD). It is
           speculated that the HBD contributes to binding the
           RNA/DNA hybrid. Prokaryotes and some single-cell
           eukaryotes do not require RNase H for viability, but
           RNase H is essential in higher eukaryotes. RNase H
           knockout mice lack mitochondrial DNA replication and die
           as embryos.

>gnl|CDD|187700 cd09276, Rnase_HI_RT_non_LTR, non-LTR RNase HI domain of reverse
           transcriptases.  Ribonuclease H (RNase H) is classified
           into two families, type 1 (prokaryotic RNase HI,
           eukaryotic RNase H1 and viral RNase H) and type 2
           (prokaryotic RNase HII and HIII, and eukaryotic RNase
           H2). Ribonuclease HI (RNase HI) is an endonuclease that
           cleaves the RNA strand of an RNA/DNA hybrid in a
           sequence non-specific manner. RNase H is widely present
           in various organisms, including bacteria, archaea and
           eukaryotes.  RNase HI has also been observed as an
           adjunct domain to the reverse transcriptase gene in
           retroviruses, long-term repeat (LTR)-bearing
           retrotransposons and non-LTR retrotransposons. RNase HI
           in LTR retrotransposons perform degradation of the
           original RNA template, generation of a polypurine tract
           (the primer for plus-strand DNA synthesis), and final
           removal of RNA primers from newly synthesized minus and
           plus strands. The catalytic residues for RNase H
           enzymatic activity, three aspartatic acids and one
           glutamatic acid residue (DEDD), are unvaried across all
           RNase H domains. The position of the RNase domain of
           non-LTR and LTR transposons is at the carboxyl terminal
           of the reverse transcriptase (RT) domain and their RNase
           domains group together, indicating a common evolutionary
           origin. Many non-LTR transposons have lost the RNase
           domain because their activity is at the nucleus and
           cellular RNase may suffice; however LTR retotransposons
           always encode their own RNase domain because it requires
           RNase activity in RNA-protein particles in the
           cytoplasm. RNase H inhibitors have been explored as an
           anti-HIV drug target because RNase H inactivation
           inhibits reverse transcription.

           only type 2 RNase H (RNase HII); however, a few contain
           RNase HI as well. Although archaeal RNase HI sequences
           conserve the DEDD active-site motif, they lack other
           common features important for catalytic function, such
           as the basic protrusion region. Archaeal RNase HI
           homologs are more closely related to retroviral RNase HI
           than bacterial and eukaryotic type I RNase H in
           enzymatic properties.

           cations. RNase H is widely present in various organisms,
           including bacteria, archaea and eukaryote.  RNase HI has
           also been observed as adjunct domains to the reverse
           transcriptase gene in retroviruses, in long-term repeat
           (LTR)-bearing retrotransposons and non-LTR
           retrotransposons. RNase HI in LTR retrotransposons
           perform degradation of the original RNA template,
           generation of a polypurine tract (the primer for
           plus-strand DNA synthesis), and final removal of RNA
           primers from newly synthesized minus and plus strands.
           The catalytic residues for RNase H enzymatic activity,
           three aspartatic acids and one glutamatic acid residue
           (DEDD),  are unvaried across all RNase H domains.
           Phylogenetic patterns of RNase HI of LTR retroelements
           is classified into five major families, Ty3/Gypsy,
           Ty1/Copia, Bel/Pao, DIRS1 and the vertebrate
           retroviruses.  Bel/Pao family has been described only in
           metazoan genomes.  RNase H inhibitors have been explored
           as an anti-HIV drug target because RNase H inactivation
           inhibits reverse transcription.

>gnl|CDD|187701 cd09277, RNase_HI_bacteria_HBD, Bacterial RNase HI containing a
           hybrid binding domain (HBD) at the N-terminus.
           Ribonuclease H (RNase H) enzymes are divided into two
           major families, Type 1 and Type 2, based on amino acid
           sequence similarities and biochemical properties. RNase
           H is an endonuclease that cleaves the RNA strand of an
           RNA/DNA hybrid in a sequence non-specific manner in the
           presence of divalent cations.  RNase H is involved in
           DNA replication, repair and transcription.  RNase H is
           widely present in various organisms, including bacteria,
           archaea and eukaryotes and most prokaryotic and
           eukaryotic genomes contain multiple RNase H genes.
           Despite the lack of amino acid sequence homology, Type 1
           and type 2 RNase H share a main-chain fold and steric
           configurations of the four acidic active-site (DEDD)
           residues and have the same catalytic mechanism and
           functions in cells.  One of the important functions of
           RNase H is to remove Okazaki fragments during DNA
           replication. Prokaryotic RNase H varies greatly in
           domain structures and substrate specificities.
           Prokaryotes and some single-cell eukaryotes do not
           require RNase H for viability. Some bacteria
           distinguished from other bacterial RNase HI in the
           presence of a hybrid binding domain (HBD) at the
           N-terminus which is commonly present at the N-termini of
           eukaryotic RNase HI. It has been reported that this
           domain is required for dimerization and processivity of
           RNase HI upon binding to RNA-DNA hybrids.
