UniProt functional annotation for A0R559

UniProt code: A0R559.

Organism: Mycolicibacterium smegmatis (strain ATCC 700084 / mc(2)155) (Mycobacterium smegmatis).
Taxonomy: Bacteria; Actinobacteria; Corynebacteriales; Mycobacteriaceae; Mycolicibacterium.
 
Function: Involved in the biosynthesis of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), two major building blocks of isoprenoid compounds. Catalyzes the conversion of 4-diphosphocytidyl-2- C-methyl-D-erythritol 2-phosphate (CDP-ME2P) to 2-C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-CPP) with a corresponding release of cytidine 5-monophosphate (CMP). {ECO:0000256|HAMAP-Rule:MF_00107}.
 
Catalytic activity: Reaction=4-CDP-2-C-methyl-D-erythritol 2-phosphate = 2-C-methyl-D- erythritol 2,4-cyclic diphosphate + CMP; Xref=Rhea:RHEA:23864, ChEBI:CHEBI:57919, ChEBI:CHEBI:58483, ChEBI:CHEBI:60377; EC=4.6.1.12; Evidence={ECO:0000256|ARBA:ARBA00000200, ECO:0000256|HAMAP- Rule:MF_00107, ECO:0000256|RuleBase:RU004395};
Cofactor: Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240; Evidence={ECO:0000256|ARBA:ARBA00001968};
Cofactor: Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240; Evidence={ECO:0000256|HAMAP-Rule:MF_00107}; Note=Binds 1 divalent metal cation per subunit. {ECO:0000256|HAMAP- Rule:MF_00107};
Pathway: Isoprenoid biosynthesis. {ECO:0000256|ARBA:ARBA00005128}.
Pathway: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5- phosphate: step 4/6. {ECO:0000256|ARBA:ARBA00004709, ECO:0000256|HAMAP- Rule:MF_00107}.
Subunit: Homotrimer. {ECO:0000256|HAMAP-Rule:MF_00107}.
Similarity: Belongs to the IspF family. {ECO:0000256|HAMAP- Rule:MF_00107, ECO:0000256|RuleBase:RU004395}.
