General annotation
FunctionInvolved 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].
ProductLysine-N-oxygenase MbtG (L-lysine 6-monooxygenase) (lysine N6-hydroxylase)
CommentsRv2378c, (MTCY27.02), len: 431 aa. MbtG, lysine-N-oxygenase (hydroxylase) (EC or; 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).
