In enzymology an alphaalpha-trehalose phosphorylase (configuration-retaining) (EC 2.4.1.231) is an enzyme that catalyzes the chemical reactionalphaalpha-trehalose + phosphate alpha-D-glucose + alpha-D-glucose 1-phosphateThus the two substrates of this enzyme are alphaalpha-trehalose and phosphate whereas its two products are alpha-D-glucose and alpha-D-glucose 1-phosphate.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
