Gene Rv2761c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Implicated in restriction/modification of DNA. Component of type I restriction/modification system. It is thought that the M and S subunits together form a methyltransferase (MTASE) that methylates two adenine residues in complementary strands of bipartite DNA recognition sequence. |
| Product | Possible type I restriction/modification system specificity determinant HsdS (S protein) |
| Comments | Rv2761c, (MTV002.26c), len: 364 aa. Possible hsdS, type I restriction/modification system specificity determinant (S protein), similar in part to other hsdS protein (S proteins) e.g. Q9P9X9|XF2741 from Xylella fastidiosa (412 aa), FASTA scores: opt: 252, E(): 7.4e-09, (24.95% identity in 401 aa overlap); N-terminus of Q9RC12 type I S-subunit from Lactobacillus delbrueckii (subsp. lactis) (389 aa), FASTA scores: opt: 232, E(): 1.4e-07, (28.1% identity in 185 aa overlap); N-terminus of P72419|sty|SBLI from Salmonella typhimurium (434 aa), FASTA scores: opt: 221, E(): 8e-07, (28.45% identity in 130 aa overlap); C-terminus of P17222|PRRB_ECOLI from Escherichia coli strain CTR5X (401 aa), FASTA scores: opt: 197, E(): 2.8e-05, (27.05% identity in 148 aa overlap); etc. Seems to belong to type-I restriction system S methylase family. |
