Biological function summary

IPT plays a central role in cytokinin biosynthesis by converting dimethylallyl diphosphate (DMAPP) and adenosine monophosphate (AMP) into isopentenyl adenine a precursor of cytokinin. Cytokinins together with auxins regulate cell division differentiation and apical dominance. IPT is often found as a part of a complex network of enzymatic reactions contributing to these processes. Its activity profoundly affects plant morphology and physiology by influencing the allocation of resources and determining plant architecture.

Pathways

IPT fits into the cytokinin biosynthetic pathway collaborating with other enzymes involved in plant hormone regulation. It plays an important role in modulating the balance between cytokinin and auxin levels which controls many developmental processes. The enzyme is closely associated with the IPT family of proteins and interfaces with the homodomain transcription factors that regulate plant growth responses to environmental stimuli. This places IPT in pivotal intersection points of hormonal and stress response pathways in plants.
