>gnl|CDD|239224 cd02894, GGTase-II, Geranylgeranyltransferase type II
(GGTase-II)_like proteins containing the protein
prenyltransferase (PTase) domain, beta subunit (alpha 6
- alpha 6 barrel fold). GGTase-IIs are a subgroup of the
protein prenyltransferase family of lipid-modifying
enzymes. PTases catalyze the carboxyl-terminal
lipidation of Ras, Rab, and several other cellular
signal transduction proteins, facilitating membrane
associations and specific protein-protein interactions.
Prenyltransferases employ a Zn2+ ion to alkylate a thiol
group catalyzing the formation of thioether linkages
between cysteine residues at or near the C-terminus of
protein acceptors and the C1 atom of isoprenoid lipids
(geranylgeranyl (20-carbon) in the case of GGTase-II ).
GGTase-II catalyzes alkylation of both cysteine residues
in Rab proteins containing carboxy-terminal "CC", "CXCX"
or "CXC" motifs. PTases are heterodimeric with both
alpha and beta subunits required for catalytic activity.
In contrast to other prenyltransferases, GGTas-II
requires an escort protein to bring the substrate
protein to the catalytic heterodimer and to escort the
geryanylgeranylated product to the membrane.

>gnl|CDD|239220 cd02890, PTase, Protein prenyltransferase (PTase) domain, beta
subunit (alpha 6 - alpha 6 barrel fold). The protein
prenyltransferase family of lipid-modifying enzymes
includes protein farnesyltransferase (FTase) and
geranylgeranyltransferase types I and II (GGTase-I and
GGTase-II). They catalyze the carboxyl-terminal
lipidation of Ras, Rab, and several other cellular
signal transduction proteins, facilitating membrane
associations and specific protein-protein interactions.
Prenyltransferases employ a Zn2+ ion to alkylate a thiol
group catalyzing the formation of thioether linkages
between the C1 atom of farnesyl (15-carbon by FTase) or
geranylgeranyl (20-carbon by GGTase-I, II) isoprenoid
lipids and cysteine residues at or near the C-terminus
of protein acceptors. FTase and GGTase-I prenylate the
cysteine in the terminal sequence, "CAAX"; and GGTase-II
prenylates both cysteines in the "CC" (or "CXC")
terminal sequence. These enzymes are heterodimeric with
both alpha and beta subunits required for catalytic
activity. In contrast to other prenyltransferases,
GGTase-II does not recognize its protein acceptor
directly but requires Rab to complex with REP (Rab
escort protein) before prenylation can occur. These
enzymes are found exclusively in eukaryotes.

cyclases, protein prenyltransferases beta subunit, two
broadly specific proteinase inhibitors
alpha2-macroglobulin (alpha (2)-M) and pregnancy zone
protein (PZP) and, the C3 C4 and C5 components of
vertebrate complement. Class II terpene cyclases include
squalene cyclase (SQCY) and 2,3-oxidosqualene cyclase
(OSQCY), these integral membrane proteins catalyze a
cationic cyclization cascade converting linear
triterpenes to fused ring compounds. The protein
prenyltransferases include protein farnesyltransferase
(FTase) and geranylgeranyltransferase types I and II
(GGTase-I and GGTase-II) which catalyze the
carboxyl-terminal lipidation of Ras, Rab, and several
other cellular signal transduction proteins,
facilitating membrane associations and specific
protein-protein interactions. Alpha (2)-M is a major
carrier protein in serum and involved in the
immobilization and entrapment of proteases. PZP is a
pregnancy associated protein. Alpha (2)-M and PZP are
known to bind to and, may modulate, the activity of
placental protein-14 in T-cell growth and cytokine
production thereby protecting the allogeneic fetus from
attack by the maternal immune system.

farnesylation has been shown to play critical roles in a
variety of cellular processes including Ras/mitogen
activated protein kinase signaling pathways in mammals
and, abscisic acid signal transduction in Arabidopsis.

>gnl|CDD|199213 cd10915, Peptidase_C25_N_2, uncharacterized subgroup of the
Peptidase C25 family N-terminal domain. Domains in this
subgroup are uncharacterized members of the Peptidase
family C25 N-terminal domain family. Peptidases family
C25 are a unique class of cysteine proteases,
exemplified by gingipain, which is produced by
Porphyromonas gingivalis. P. gingivalis is one of the
primary gram-negative pathogens that causes
periodontitis, a disease that is also associated with
other diseases such as diabetes and cardiovascular
disease. Gingipains are a group of extracellular Arg-
and Lys-specific proteinases called Arg-gingipain (Rgp)
and Lys-gingipain (Kgp); RgpA and RgpB are homologous
Arg-specific gingipains encoded by two closely related
genes, rgpA and rgpB, while Lys-specific gingipain is
encoded by the single kgp gene. Mutant studies have
shown that, among the large quantities of proteolytic
enzymes produced by P. gingivalis, these three proteases
are major virulence factors of this bacterium. All three
genes encode an N-terminal pre-pro fragment, followed by
the protease domain; however, rgpA and kgp also encode
additional C-terminal HA (hemaglutinin/adhesion)
subunits which consist of several sequence-related
adhesion domains. Although unique, their cysteine
protease active site residues (His and Cys) forming the
catalytic dyad are well-conserved, cleaving the
C-terminal peptide bond with Arg or Lys residues.
Gingipains are evolutionarily related to other highly
specific proteases including caspases, clostripain,
legumains, and separase. Gingipains function by
dysregulating host defense and inflammatory responses,
and degrading host proteins, e.g. tissue, cells, matrix,
plasma and immunological proteins. They are proposed to
enhance gingival crevicular fluid (GCF) production
through activation of the kallikrein/kinin pathways,
thus increasing vascular permeability and causing
gingival inflammation, a distinctive feature of
periodontitis. RgpA and RgpB are also able to cleave and
activate coagulation factors IX and X in order to
activate prothrombin to produce thrombin, which in turn
increases production of GCF. The gingipains also play a
pivotal role in the survival of P. gingivalis in the
host by attacking the host defense system through
cleavage of several immunological molecules, while at
the same time evading the host-immune response by
dysregulating the cytokine network.
