>gnl|CDD|132910 cd07032, RNAP_I_II_AC40, AC40 subunit of Eukaryotic RNA polymerase
(RNAP) I and RNAP III. The eukaryotic AC40 subunit of
RNA polymerase (RNAP) I and RNAP III is involved in the
assembly of RNAP subunits. RNAP is a large multi-subunit
complex responsible for the synthesis of RNA. It is the
principal enzyme of the transcription process, and is a
final target in many regulatory pathways that control
gene expression in all living cells. At least three
distinct RNAP complexes are found in eukaryotic nuclei:
RNAP I, RNAP II, and RNAP III. RNAP I is responsible for
the synthesis of ribosomal RNA precursor, while RNAP III
functions in the synthesis of 5S and tRNA. The AC40
subunit is the equivalent of the RPB3 subunit of RNAP
II. The RPB3 subunit is similar to the bacterial RNAP
alpha subunit in that it contains two subdomains: one
subdomain is similar the eukaryotic Rpb11/AC19/archaeal
L subunit which is involved in dimerization; and the
other is an inserted beta sheet subdomain. The RPB3
subunit heterodimerizes with the RPB11 subunit, and
together with RPB10 and RPB12, anchors the two largest
subunits, RPB1 and RPB2, and stabilizes their
association. The homology of AC40 to RPB3 suggests a
similar function. The AC40 subunit is likely to
associate with the RPB11 counterpart, AC19, to form a
heterodimer, which stabilizes the association of the two
largest subunits of RNAP I and RNAP III.

>gnl|CDD|132906 cd07028, RNAP_RPB3_like, RPB3 subunit of RNA polymerase. The
eukaryotic RPB3 subunit of RNA polymerase (RNAP), as
well as its archaeal (D subunit) and bacterial (alpha
subunit) counterparts, is involved in the assembly of
RNAP subunits. RNAP is a large multi-subunit complex
responsible for the synthesis of RNA. It is the
principal enzyme of the transcription process, and is a
final target in many regulatory pathways that control
gene expression in all living cells. At least three
distinct RNAP complexes are found in eukaryotic nuclei:
RNAP I, RNAP II, and RNAP III, for the synthesis of
ribosomal RNA precursor, mRNA precursor, and 5S and
tRNA, respectively. A single distinct RNAP complex is
found in prokaryotes and archaea, which may be
responsible for the synthesis of all RNAs. The RPB3
subunit is similar to the bacterial RNAP alpha subunit
in that it contains two subdomains: one subdomain is
similar to the eukaryotic Rpb11/AC19/archaeal L subunit
which is involved in dimerization; and the other is an
inserted beta sheet subdomain. The assembly of the two
largest eukaryotic RNAP subunits that provide most of
the enzyme's catalytic functions depends on the presence
of RPB3/RPB11 heterodimer subunits. This is also true
for the archaeal (D/L subunits) and bacterial (alpha
subunit) counterparts.

>gnl|CDD|132908 cd07030, RNAP_D, D subunit of Archaeal RNA polymerase. The D
subunit of archaeal RNA polymerase (RNAP) is involved in
the assembly of RNAP subunits. RNAP is a large
multi-subunit complex responsible for the synthesis of
RNA. It is the principal enzyme of the transcription
process, and is a final target in many regulatory
pathways that control gene expression in all living
cells. A single distinct RNAP complex is found in
archaea, which may be responsible for the synthesis of
all RNAs. The archaeal RNAP harbors homologues of all
eukaryotic RNAP II subunits with two exceptions (RPB8
and RPB9). The 12 archaeal subunits are designated by
letters and can be divided into three functional groups
that are engaged in: (I) catalysis (A'/A", B'/B" or B);
(II) assembly (L, N, D and P); and (III) auxiliary
functions (F, E, H and K). The D subunit is equivalent
to the RPB3 subunit of eukaryotic RNAP II. It contains
two subdomains: one subdomain is similar the eukaryotic
Rpb11/AC19/archaeal L subunit which is involved in
dimerization, and the other is an inserted beta sheet
subdomain. The assembly of the two largest archaeal RNAP
subunits that provide most of the enzyme's catalytic
functions depends on the presence of the archaeal D/L
heterodimer.

LacI-GalR family of bacterial transcription regulators.
Ligand-binding domain of DNA transcription repressors
specific for raffinose (RafR) and alpha-glucosides
(AglR) which are members of the LacI-GalR family of
bacterial transcription regulators. The LacI-GalR family
repressors are composed of two functional domains: an
N-terminal HTH (helix-turn-helix) domain, which is
responsible for the DNA-binding specificity, and a
C-terminal ligand-binding domain, which is homologous to
the sugar-binding domain of ABC-type transport systems
that contain the type I periplasmic binding protein-like
fold. As also observed in the periplasmic binding
proteins, the C-terminal domain of the bacterial
transcription repressor undergoes a conformational
change upon ligand binding which in turn changes the DNA
binding affinity of the repressor.

phenomena exhibited by eubacteria, is initiated by
various causes that include DNA damage-induced
replication arrest, and is positively regulated by the

DinI physically interacts with RecA to inhibit its
