Gene Rv2924c (mutM)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in base excision repair (repair of oxidized purines). This enzyme may play a significant role in processes leading to recovery from mutagenesis and/or cell death by alkylating agents [catalytic activity hydrolysis of DNA containing ring-opened N7-methylguanine residues, releasing 2,6-diamino-4-hydroxy-5-(N-methyl)formamidopyrimide]. |
| Product | Probable formamidopyrimidine-DNA glycosylase Fpg (FAPY-DNA glycosylase) |
| Comments | Rv2924c, (MTCY338.13c), len: 289 aa. Probable fpg (alternate gene name: mutM), formamidopyrimidine-DNA glycosylase (see citation below), equivalent to O69470|FPG_MYCLE formamidopyrimidine-DNA glycosylase from Mycobacterium leprae (282 aa), FASTA scores: opt: 1563, E(): 1.3e-96, (80.6% identity in 289 aa overlap). Also highly similar to other formamidopyrimidine-DNA glycosylases e.g. Q9ZBQ6|FPG_STRCO from Streptomyces coelicolor (286 aa), FASTA scores: opt: 1047, E(): 2.9e-62, (57.55% identity in 292 aa overlap); P95744|FPG_SYNEN from Synechococcus elongatus naegeli (284 aa), FASTA scores: opt: 569, E(): 1.9e-30, (37.95% identity in 290 aa overlap); P05523|FPG_ECOLI|MUTM|FPG|B3635 from Escherichia coli strain K12 (269 aa), FASTA scores: opt: 424, E(): 8.2e-21, (33.9% identity in 289 aa overlap); etc. Belongs to the FPG family. Cofactor: binds 1 zinc ion. |
| Functional category | Information pathways |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
