4-151 | 1.10e-45 | ||||
uncharacterized subfamily of the LabA-like PIN domain of Synechococcus elongatus LabA (low-amplitude and bright) and related proteins; The LabA-like PIN domain family includes Synechococcus elongatus PCC 7942 LabA which participates in cyanobacterial circadian timing, it is required for negative feedback regulation of the autokinase/autophosphatase KaiC, a central component of the circadian clock system, and appears to be necessary for KaiC-dependent repression of gene expression. It also includes the N-terminal domain of limkain b1, a human autoantigen localized to a subset of ABCD3 and PXF marked peroxisomes, human ZNF451, uncharacterized Bacillus subtilis YqxD, uncharacterized Escherichia coli YaiI, and the N-terminal domain of a well-conserved group of mainly bacterial proteins with no defined function, which contain a C-terminal LabA_like_C domain. Curiously Pseudomonas putida S16 NicB, which is described as a putative NADH-dependent hydroxylase involved in the microbial degradation of nicotine also falls into this family. The PIN (PilT N terminus) domain belongs to a large nuclease superfamily. The structural properties of the PIN domain indicate its active center, consisting of three highly conserved catalytic residues which coordinate metal ions; in some members, additional metal coordinating residues can be found while some others lack several of these key catalytic residues. The PIN active site is geometrically similar in the active center of structure-specific 5' nucleases, PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons. : Pssm-ID: 350291 Cd Length: 172 Bit Score: 147.80 E-value: 1.10e-45

NYN domain; These domains are found in the eukaryotic proteins typified by the Nedd4-binding protein 1 and the bacterial YacP-like proteins (Nedd4-BP1, YacP nucleases; NYN domains). The NYN domain shares a common protein fold with two other previously characterized groups of nucleases, namely the PIN (PilT N-terminal) and FLAP/5' --> 3' exonuclease superfamilies. These proteins share a common set of 4 acidic conserved residues that are predicted to constitute their active site. Based on the conservation of the acidic residues and structural elements Aravind and colleagues suggest that PIN and NYN domains are likely to bind only a single metal ion, unlike the FLAP/5' --> 3' exonuclease superfamily, which binds two metal ions. Based on conserved gene neighborhoods Aravind and colleagues infer that the bacterial members are likely to be components of the processome/degradsome that process tRNAs or ribosomal RNAs.
