MetaCyc Enzyme: trehalose-6-phosphate phosphatase

Species: Saccharomyces cerevisiae

This is probably a specific maltose-induced phosphatase from the ADP-α-D-glucose-dependent pathway trehalose biosynthesis II, not the TPS2 phosphatase from the UDP-α-D-glucose-dependent pathway trehalose biosynthesis I [Ferreira97].

Enzymatic reaction of: trehalose-6-phosphate phosphatase

EC Number:

α,α-trehalose 6-phosphate + H2O <=> α,α-trehalose + phosphate

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

The reaction is physiologically favored in the direction shown.

In Pathways: trehalose biosynthesis II
