General annotation
TypeCDS
FunctionInvolved in purine biosynthesis (sixth step). This subunit can alone transform air to CAIR, but in association with PURK, which possesses an ATPase activity, an enzyme complex is produced which is capable of converting air to CAIR efficiently under physiological condition [catalytic activity: 1-(5-phosphoribosyl)-5-amino-4-imidazole-carboxylate = 1-(5-phosphoribosyl)-5-aminoimidazole + CO(2)].
ProductProbable phosphoribosylaminoimidazole carboxylase catalytic subunit PurE (air carboxylase) (AIRC)
CommentsRv3275c, (MTCY71.15c, PUR6), len: 174 aa. Probable purE, phosphoribosylaminoimidazole carboxylase catalytic subunit, equivalent to P46702|PUR6_MYCLE|pure|ML0736|B1308_F3_98 from Mycobacterium leprae (171 aa), FASTA scores: opt: 878, E(): 1.5e-43, (81.55% identity in 168 aa overlap). Also similar to others e.g. Q9AXD0|AIRC from Nicotiana tabacum (Common tobacco) (623 aa), FASTA scores: opt: 712, E(): 1.4e-33, (69.35% identity in 160 aa overlap) (similarity in C-terminal part for this one); Q44679|PUR6_CORAM from Corynebacterium ammoniagenes (Brevibacterium ammoniagenes) (177 aa), FASTA scores: opt: 651, E(): 1.5e-30, (68.25% identity in 148 aa overlap); Q55498|PUR6_SYNY3|pure|SLL0901 from Synechocystis sp. strain PCC 6803 (176 aa), FASTA scores: opt: 639, E(): 7.1e-30, (60.5% identity in 167 aa overlap); etc.
Functional categoryIntermediary metabolism and respiration
ProteomicsThe product of this CDS corresponds to spot 3_407 identified by proteomics at the Max Planck Institute for Infection Biology, Berlin, Germany (See Mattow et al., 2001). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
MutantDisruption of this gene results in growth defect of H37Rv in vitro, 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).
