2.5.1.27 | (E)-4-hydroxy-3-methyl-but-2-enyl diphosphate + AMP |
HMBPP, the enzyme uses the hydroxylated side chain precursor to form trans-zeatin-5'-monophosphate in the reaction with AMP, reaction rate is 0.5% of the rate with dimethylallyl díphosphate |

2.5.1.27 | 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate + AMP |
1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate is an intermediate in the methylerythritol phosphate pathway. Agrobacterium tumefaciens modifies cytokinin biosynthesis by sending a key enzyme into plastids of the host plant to promote tumorigenesis |
