FunctionNecessary for the biosynthesis of purines, thymydylate, methionine, histidine, pantothenate, and formyl tRNA-met [catalytic activity: 5,10-methylenetetrahydrofolate + NADP(+) = 5,10-methenyltetrahydrofolate + NADPH] [catalytic activity: 5,10-methenyltetrahydrofolate + H(2)O = 10-formyltetrahydrofolate].
ProductProbable bifunctional protein FolD: methylenetetrahydrofolate dehydrogenase + methenyltetrahydrofolate cyclohydrolase
CommentsRv3356c, (MTV004.13c), len: 281 aa. Probable folD, bifunctional enzyme include methylenetetrahydrofolate dehydrogenase and methenyltetrahydrofolate cyclohydrolase , equivalent to O32879|fold|ML0674 methylenetetrahydrofolate dehydrogenase (putative methylenetetrahydrofolate dehydrogenase/methenyltetrahydrofolate cyclohydrolase) from Mycobacterium leprae (282 aa), FASTA scores: opt: 1624, E(): 1.2e-93, (86.45% identity in 281 aa overlap). Also similar to many others e.g. Q9K3J6|fold from Streptomyces coelicolor (284 aa), FASTA scores: opt: 1223, E(): 9.5e-69, (66.65% identity in 279 aa overlap); Q9K966|fold from Bacillus halodurans (279 aa), FASTA scores: opt: 886, E(): 7.7e-48, (47.15% identity in 280 aa overlap); P54382|FOLD_BACSU from Bacillus subtilis (283 aa), FASTA scores: opt: 820, E(): 9.7e-44, (45.7% identity in 280 aa overlap); P51696|FOLD_PHOPO from Photobacterium phosphoreum (285 aa), FASTA scores: opt: 778, E(): 4e-41, (44.9% identity in 283 aa overlap); P24186|FOLD_ECOLI|ads|B0529 from Escherichia coli (287 aa), FASTA scores: opt: 741, E(): 0,44.4, (44.4% identity in 277 aa overlap); etc. Also highly similar to MLCB1779_9 from Mycobacterium leprae cosmid B1779 (282 aa) (86.5% identity in 281 aa overlap). Similar to other dehydrogenase/cyclohydrolase enzymes or domains.
