nucleoside salvage

Any process which produces a nucleotide, a nucleobase linked to either beta-D-ribofuranose (ribonucleoside) or 2-deoxy-beta-D-ribofuranose (a deoxyribonucleotide), from derivatives of it without de novo synthesis.

pectate disaccharide-lyase activity

Catalysis of the reaction: a pectate = a pectate + 4-(4-deoxy-alpha-D-galact-4-enuronosyl)-D-galacturonate. This reaction is the eliminative cleavage of 4-(4-deoxy-alpha-D-galact-4-enuronosyl)-D-galacturonate from the reducing end of pectate, i.e. de-esterified pectin.

nicotinate nucleotide salvage

The generation of nicotinate nucleotide without de novo synthesis.

aldose beta-D-fructosyltransferase activity

Catalysis of the reaction: alpha-D-aldosyl1 beta-D-fructoside + D-aldose2 = D-aldose1 + alpha-D-aldosyl2 beta-D-fructoside.

lacto-N-biosidase activity

Catalysis of the reaction: H2O + beta-D-Gal-(1,3)-beta-D-GlcNAc-(1,3)-beta-D-Gal-(1,4)-D-Glc = beta-D-Gal-(1,4)-D-Glc + beta-D-Gal-(1,3)-D-GlcNAc.

mannotetraose 2-alpha-N-acetylglucosaminyltransferase activity

Catalysis of the reaction: 1,3-alpha-D-mannosyl-1,2-alpha-D-mannosyl-1,2-alpha-D-mannosyl-D-mannose + UDP-N-acetyl-D-glucosamine = 1,3-alpha-D-mannosyl-1,2-(N-acetyl-alpha-D-glucosaminyl-alpha-D-mannosyl)-1,2-alpha-D-mannosyl-D-mannose + UDP.

globoside alpha-N-acetylgalactosaminyltransferase activity

Catalysis of the reaction: N-acetyl-D-galactosaminyl-(1,3)-D-galactosyl-(1,4)-D-galactosyl-(1,4)-D-glucosylceramide + UDP-N-acetylgalactosamine = N-acetyl-D-galactosaminyl-N-acetyl-D-galactosaminyl-(1,3)-D-galactosyl-(1,4)-D-galactosyl-(1,4)-D-glucosylceramide + UDP.

dol-P-Man:Man(5)GlcNAc(2)-PP-Dol alpha-1,3-mannosyltransferase activity

Catalysis of the reaction: an alpha-D-man-(1->2)-alpha-D-Man-(1->2)-alpha-D-Man-(1->3)-(alpha-D-Man-(1->6))-beta-D-Man-(1->4)-beta-D-GlcNAc-(1->4)-D-GlcNAc-diphosphodolichol + dolichyl D-mannosyl phosphate = H+ + alpha-D-Man-(1->2)-alpha-D-Man-(1->2)-alpha-D-Man-(1->3)-(alpha-D-Man-(1->3)-alpha-D-Man-(1->6))-beta-D-Man-(1->4)-beta-D-GlcNAc-(1->4)-D-GlcNAc-diphosphodolichol + dolichyl phosphate.

glucosaminylgalactosylglucosylceramide beta-galactosyltransferase activity

Catalysis of the reaction: N-acetyl-D-glucosaminyl-(1,3)-D-galactosyl-(1,4)-D-glucosylceramide + UDP-galactose = D-galactosyl-N-acetyl-D-glucosaminyl-(1,3)-D-galactosyl-(1,4)-D-glucosylceramide + UDP.

glucose-fructose oxidoreductase activity

Catalysis of the reaction: D-fructose + D-glucose = D-glucitol + D-glucono-1,5-lactone.
