Procollagen galactosyltransferase

In enzymology, a procollagen galactosyltransferase (EC number|2.4.1.50) is an enzyme that catalyzes the chemical reaction

:UDP-galactose + procollagen 5-hydroxy-L-lysine $ightleftharpoons$ UDP + procollagen 5-(D-galactosyloxy)-L-lysine

Thus, the two substrates of this enzyme are UDP-galactose and procollagen 5-hydroxy-L-lysine, whereas its two products are UDP and procollagen 5-(D-galactosyloxy)-L-lysine.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-galactose:procollagen-5-hydroxy-L-lysine D-galactosyltransferase. Other names in common use include hydroxylysine galactosyltransferase, collagen galactosyltransferase, collagen hydroxylysyl galactosyltransferase, UDP galactose-collagen galactosyltransferase, uridine diphosphogalactose-collagen galactosyltransferase, and UDPgalactose:5-hydroxylysine-collagen galactosyltransferase. This enzyme participates in lysine degradation.
