>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.

>gnl|CDD|187690 cd06222, RNase_H, RNase H is an endonuclease that cleaves the RNA
strand of an RNA/DNA hybrid in a sequence non-specific
manner. 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 widely present in various organisms,
including bacteria, archaea and eukaryotes. 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 residues and have the same catalytic
mechanism and functions in cells. 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 inhibitors
have been explored as an anti-HIV drug target because
RNase H inactivation inhibits reverse transcription.

repeat retroelements. 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

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

eukaryotic RNase HI have highly conserved regions at the

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

>gnl|CDD|173882 cd08517, PBP2_NikA_DppA_OppA_like_13, The substrate-binding
component of an uncharacterized ABC-type
nickel/dipeptide/oligopeptide-like import system
contains the type 2 periplasmic binding fold. This CD
represents the substrate-binding domain of an
uncharacterized ATP-binding cassette (ABC) type
nickel/dipeptide/oligopeptide-like transporter. The
oligopeptide-binding protein OppA and the
dipeptide-binding protein DppA show significant sequence
similarity to NikA, the initial nickel receptor. The
DppA binds dipeptides and some tripeptides and is
involved in chemotaxis toward dipeptides, whereas the
OppA binds peptides of a wide range of lengths (2-35
amino acid residues) and plays a role in recycling of
cell wall peptides, which precludes any involvement in
chemotaxis. Most of other periplasmic binding proteins
are comprised of only two globular subdomains
corresponding to domains I and III of the
dipeptide/oligopeptide binding proteins. The structural
topology of these domains is most similar to that of the
type 2 periplasmic binding proteins (PBP2), which are
responsible for the uptake of a variety of substrates
such as phosphate, sulfate, polysaccharides,
lysine/arginine/ornithine, and histidine. The PBP2 bind
their ligand in the cleft between these domains in a
manner resembling a Venus flytrap. After binding their
specific ligand with high affinity, they can interact
with a cognate membrane transport complex comprised of
two integral membrane domains and two cytoplasmically
located ATPase domains. This interaction triggers the
ligand translocation across the cytoplasmic membrane
energized by ATP hydrolysis. Besides transport
proteins, the PBP2 superfamily includes the
ligand-binding domains from ionotropic glutamate
receptors, LysR-type transcriptional regulators, and
unorthodox sensor proteins involved in signal
transduction.
