FunctionCatalyzes the transfer of a methyl group from 5-methyltetrahydrofolate to homocysteine resulting in methionine formation (pathway: terminal step in the de novo biosynthesis of methionine) [catalytic activity: 5-methyltetrahydropteroyltri-L-glutamate + L- homocysteine = tetrahydropteroyltri-L-glutamate + L-methionine.]
ProductProbable 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase MetE (methionine synthase, vitamin-B12 independent isozyme)
CommentsRv1133c, (MTC22G8.22), len: 759 aa (start site chosen by homology). Probable metE, 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase, highly similar to others e.g. METE_ECOLI|P25665 Escherichia coli (752 aa), FASTA scores: opt: 2251, E(): 0, (48.1% identity in 756 aa overlap). Equivalent to Z94723|MLCB33_14 metE from M. leprae (760 aa) (85.3% identity in 755 aa overlap). Belongs to the vitamin-B12 independent methionine synthase family.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified by proteomics at the Statens Serum Institute (Denmark) (See Rosenkrands et al., 2000). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cytosol, cell wall, and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
