In enzymology a polygalacturonate 4-alpha-galacturonosyltransferase (EC 2.4.1.43) is an enzyme that catalyzes the chemical reactionUDP-D-galacturonate + (14-alpha-D-galacturonosyl)n UDP + (14-alpha-D-galacturonosyl)n+1Thus the two substrates of this enzyme are UDP-D-galacturonate and (14-alpha-D-galacturonosyl)n whereas its two products are UDP and (14-alpha-D-galacturonosyl)n+1.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
