two subsequent dephosphorylations occur adjacent to the D-5 hydroxyl group to yield myo-inositol-1,2,3-trikisphosphate as the final product, rates of removal of the second and third phosphates are significantly lower, possibly due to reduced specificity for IP5 and IP4 and inhibition by the phosphate released, IP4: only one isomer, either I-1,2,3,4-P4 or its enantiomer I-1,2,3,6-P4, no further hydrolysis of IP3 |

the tyrosine phosphatase (PTP)-like inositol polyphosphatase from Selenomonas ruminantium subsp. lactilytica dephosphorylates myo-inositol hexakisphosphate (Ins P(6)) in vitro preferentially cleaving the 5-phosphate position. Enzyme PhyAsrl has a general specificity for polyphosphorylated myo-inositol substrates, but can also dephosphorylate molecules containing high energy diphosphate bonds in vitro. It can produce Ins(2)P via a highly unique and ordered pathway of sequential dephosphorylation: Ins P(6), Ins(1,2,3,4,6)P(5), D-Ins(1,2,3,6)P(4), Ins(1,2,3)P(3), and D/L-Ins(1,2)P(2) |
