NCBI Protein Information
isopentenyltransferase 1
NCBI Summary
Encodes a putative adenylate isopentenyltransferase. It catalyzes the formation of isopentenyladenosine 5'-monophosphate (iPMP) from AMP and dimethylallylpyrophosphate (DMAPP), but it has a lower Km for ADP and likely works using ADP or ATP in plants. It is involved in cytokinin biosynthesis.

UniProt Comments
Involved in cytokinin biosynthesis. Catalyzes the transfer of an isopentenyl group from dimethylallyl diphosphate (DMAPP) to ATP, ADP and AMP. Adenine, adenosine, isopentenylpyrophosphate and 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate (HMBDP) are not used as substrates.
