Gene Rv3062
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | This protein seals during DNA replication, DNA recombination and DNA repair NICKS in double-stranded DNA [catalytic activity: ATP + (deoxyribonucleotide)(N) + (deoxyribonucleotide)(M) = AMP + pyrophosphate + (deoxyribonucleotide)(N+M)]. |
| Product | Probable ATP-dependent DNA ligase LigB (polydeoxyribonucleotide synthase [ATP]) (polynucleotide ligase [ATP]) (sealase) (DNA repair protein) (DNA joinase) |
| Comments | Rv3062, (MTCY22D7.19c), len: 507 aa. Probable ligB, DNA ligase ATP-dependent (see citation below), highly similar to numerous archaebacterial and eukaryotic polynucleotide DNA ligases, e.g. Q9FCB1|DNLI_STRCO|LIG|2SCG58.02 from Streptomyces coelicolor (512 aa), FASTA scores: opt: 1677, E(): 2.5e-90, (55.65% identity in 512 aa overlap); Q9HR35|DNLI_HALN1|LIG|VNG0881G from Halobacterium sp. strain NRC-1 (561 aa), FASTA scores: opt: 985, E(): 5.6e-50, (42.25% identity in 440 aa overlap); Q9V185|DNLI_PYRAB|LIG|PAB2002 from Pyrococcus abyssi (559 aa), FASTA scores: opt: 978, E(): 1.4e-49, (39.05% identity in 443 aa overlap); etc. Also similar to Rv3731|MTV025.079|LIGC possible DNA ligase from M. tuberculosis (358 aa). Similarity at N-terminus is poor so first start codon was taken. Contains (PS00697) ATP-dependent DNA ligase AMP-binding site signature, and (PS00017) ATP/GTP-binding site motif A (P-loop). Belongs to the ATP-dependent DNA ligase family. |
| Functional category | Information pathways |
