CC -!- FUNCTION: Catalyzes the 1,3-allylic rearrangement of the homoallylic
CC substrate isopentenyl (IPP) to its highly electrophilic allylic isomer,
CC dimethylallyl diphosphate (DMAPP). {ECO:0000255|HAMAP-Rule:MF_00202}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=isopentenyl diphosphate = dimethylallyl diphosphate;
CC Xref=Rhea:RHEA:23284, ChEBI:CHEBI:57623, ChEBI:CHEBI:128769;
CC EC=5.3.3.2; Evidence={ECO:0000255|HAMAP-Rule:MF_00202};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00202};
CC Note=Binds 1 Mg(2+) ion per subunit. The magnesium ion binds only when
CC substrate is bound. {ECO:0000255|HAMAP-Rule:MF_00202};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00202};
CC Note=Binds 1 Mn(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00202};
CC -!- PATHWAY: Isoprenoid biosynthesis; dimethylallyl diphosphate
CC biosynthesis; dimethylallyl diphosphate from isopentenyl diphosphate:
CC step 1/1. {ECO:0000255|HAMAP-Rule:MF_00202}.
CC -!- PATHWAY: Porphyrin-containing compound metabolism; chlorophyll
CC biosynthesis. {ECO:0000255|HAMAP-Rule:MF_00202}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00202}.
CC -!- SIMILARITY: Belongs to the IPP isomerase type 1 family.
CC {ECO:0000255|HAMAP-Rule:MF_00202}.
CC -!- SEQUENCE CAUTION:
CC Sequence=ABP69920.1; Type=Erroneous initiation; Evidence={ECO:0000305};
