The metabolism of inositol 1,3,4-trisphosphate to inositol 1,3-bisphosphate.

Abstract

We previously demonstrated a pathway for the metabolism of inositol 1,3,4-trisphosphate (Ins(1,3,4)P3) to inositol 3,4-bisphosphate (Ins(3,4)P2) in calf brain extracts. Inositol polyphosphate 1-phosphatase, a Mg2+-dependent, lithium ion-inhibited enzyme, specifically hydrolyzes Ins(1,3,4)P3 to Ins(3,4)P2 and Ins(1,4)P2 to Ins 4-P (Inhorn, R. C., Bansal, V… (More)
