Gene Rv2378c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in the biogenesis of the hydroxyphenyloxazoline-containing siderophore mycobactins. This hydroxylase is possibly required for N-hydroxylation of the two lysine residues at some stage during mycobactin assembly [catalytic activity: L-lysine + O(2) = N6-hydroxy-L-lysine + H(2)O. No information can be found if this enzyme is NADPH dependent or independent]. |
| Product | Lysine-N-oxygenase MbtG (L-lysine 6-monooxygenase) (lysine N6-hydroxylase) |
| Comments | Rv2378c, (MTCY27.02), len: 431 aa. MbtG, lysine-N-oxygenase (hydroxylase) (EC 1.13.12.10 or 1.14.13.59; depending if enzyme is NADPH dependent or independent) (see citations below), showing some similarity with various proteins including ornithine and lysine-N-oxygenases, e.g. Q9K6Q1|TRKA|BH3677 potassium uptake protein from Bacillus halodurans (350 aa), FASTA scores: opt: 153, E(): 0.016, (25.2% identity in 246 aa overlap); P56584|SID1_USTMA L-ornithine 5-monooxygenase from Ustilago maydis (Smut fungus) (570 aa), FASTA scores: opt: 136, E(): 0.31, (22.85% identity in 127 aa overlap); Q9HHV0|HXYA|VNG6214G monooxygenase from Halobacterium sp. strain NRC-1 (477 aa), FASTA scores: opt: 119, E(): 3.4, (40.0% identity in 70 aa overlap); O69828|SC1A6.23 putative lysine N-hydroxlase (fragment) from Streptomyces coelicolor (134 aa), blast score: 76 (similarity in part for this one); etc. Cofactors: FAD (by similarity). |
| Functional category | Lipid metabolism |
| Proteomics | Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| Transcriptomics | DNA microarrays indicate repression by iron and IdeR|Rv2711 in M. tuberculosis H37Rv (See Rodriguez et al., 2002). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-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). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
