General annotation
FunctionCatalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopenten to its allylic isomer, dimethylallyl diphosphate (DMAPP) [catalytic activity :isopentenyl diphosphate = dimethylallyl diphosphate]
ProductProbable isopentenyl-diphosphate delta-isomerase Idi (IPP isomerase) (isopentenyl pyrophosphate isomerase)
CommentsRv1745c, (MTCY28.08c,MTCY04C12.29c), len: 203 aa. Probable idi, isopentenyl-diphosphate delta-isomerase, similar to Q46822|ORF_O182 from Escherichia coli (182 aa), FASTA scores: opt: 465, E(): 4.7e-25, (46.9% identity in 162 aa overlap), and to IPPI_SCHPO|Q10132 isopentenyl-diphosphate delta-isomerase from Schizosaccharomyces pombe (227 aa), FASTA scores: opt: 185, E(): 5.4e-06, (30.3% identity in 152 aa overlap). Belongs to the IPP isomerase type 1 family.
Functional categoryIntermediary metabolism and respiration
MutantNon-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003).
