FunctionInvolved in riboflavin biosynthesis [catalytic activity: GTP + 3 H(2)O = formate + 2,5-diamino-6-hydroxy-4-(5-phosphoribosylamino)pyrimidine + diphosphate].
ProductProbable riboflavin biosynthesis protein RibA2 : GTP cyclohydrolase II + 3,4-dihydroxy-2-butanone 4-phosphate synthase (DHBP synthase)
CommentsRv1415, (MTCY21B4.33), len: 425 aa. Probable ribA2, Riboflavin biosynthesis protein, similar to many e.g. GCH2_BACSU|P17620 Bacillus subtilis (398 aa), FASTA scores: opt: 1388, E(): 0, (55.4% identity in 399 aa overlap). Also similar to second Mycobacterium tuberculosis gtp cyclohydrolase Rv1940|ribA1 (353 aa). In the N-terminal section; belongs to the DHBP synthase family. In the C-terminal section; belongs to the GTP cyclohydrolase II family.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011).
MutantEssential 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).
