In enzymology, a procollagen galactosyltransferase is an enzyme that catalyzes the chemical reaction
UDP-galactose + procollagen 5-hydroxy-L-lysine
\rightleftharpoons
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.
