Gene Rv3606c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in dihydrofolate biosynthesis (at the first step) [catalytic activity: ATP + 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine = AMP + 2-amino-7,8-dihydro-4-hydroxy-6-(diphosphooxymethyl)pteridine]. |
| Product | 2-amino-4-hydroxy-6-hydroxymethyldihydropteridine pyrophosphokinase FolK (7,8-dihydro-6-hydroxymethylpterin-pyrophosphokinase) (HPPK) (6-hydroxymethyl-7,8-dihydropterin pyrophosphokinase) (PPPK) (2-amino-4-hydroxy-6-hydroxymethyldihydropteridine diphosphokinase) (7,8-dihydro-6-hydroxymethylpterin-diphosphokinase) (6-hydroxymethyl-7,8-dihydropterin diphosphokinase) |
| Comments | Rv3606c, (MTCY07H7B.16), len: 188 aa. Probable folK, 2-amino-4-hydroxy-6-hydroxymethyldihydropterine pyrophosphokinase, equivalent to O69528|HPPK_MYCLE|folk|ML0226MLCB2548.05c 2-amino-4-hydroxy-6-hydroxymethyldihydropteridine pyrophosphokinase from Mycobacterium leprae (191 aa) FASTA scores: opt: 772, E(): 1.2e-44, (63.15% identity in 190 aa overlap). Also similar to many e.g. P71512|HPPK_METEX|folk|FOLA from Methylobacterium extorquens (158 aa), FASTA scores: opt: 292, E(): 1.4e-12, (36.85% identity in 171 aa overlap); O33726|HPPK_STRPY|folk|SPY1100 from Streptococcus pyogenes (166 aa), FASTA scores: opt: 234, E(): 1.1e-08, (34.3% identity in 175 aa overlap); Q9X8I1|SCE9.08 from Streptomyces coelicolor (203 aa), FASTA scores: opt: 232, E(): 1.7e-08, (43.25% identity in 185 aa overlap); P26281|HPPK_ECOLI|folk|B0142 from Escherichia coli strain K12 (158 aa), FASTA scores: opt: 198, E(): 2.6e-06, (32.85% identity in 143 aa overlap); etc. Belongs to the HppK family. |
| Functional category | Intermediary metabolism and respiration |
| Mutant | Disruption of this gene results in growth defect of H37Rv in vitro, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Check for mutants available at TARGET website |
