FunctionCatalyzes methyl transfer from S-methylmethionine or S-adenosylmethionine (less efficient) to homocysteine, selenohomocysteine and less efficiently selenocysteine [catalytic activity: S-adenosyl-L-methionine + L-homocysteine = S-adenosyl-L-homocysteine + L-methionine].
ProductProbable homocysteine S-methyltransferase MmuM (S-methylmethionine:homocysteine methyltransferase) (cysteine methyltransferase)
CommentsRv2458, (MTV008.14), len: 302 aa. Probable mmuM, homocysteine S-methyltransferase, equivalent to Q9CBY5|ML1478 possible transferase from Mycobacterium leprae (293 aa), FASTA scores: opt: 1507, E(): 2.7e-86, (78.85% identity in 293 aa overlap). Also similar to others e.g. Q47690|MMUM_ECOLI|B0261 homocysteine S-methyltransferase from Escherichia coli strain K12 (310 aa), FASTA scores: opt: 863, E(): 2.4e-46, (47.65% identity in 298 aa overlap); Q9FUM7 homocysteine S-methyltransferase-4 from Zea mays (Maize) (342 aa), FASTA scores: opt: 324, E(): 6.8e-13, (44.45% identity in 306 aa overlap); Q9LUI7|HMT3 cysteine methyltransferase from Arabidopsis thaliana (Mouse-ear cress) (347 aa), FASTA scores: opt: 312, E(): 3.8e-12, (41.85% identity in 313 aa overlap); etc. Identical to AAK46833|MT2533 homocysteine S-methyltransferase from Mycobacterium tuberculosis strain CDC1551 (302 aa).
Functional categoryIntermediary metabolism and respiration
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Disruption of this gene provides a growth advantage for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
