abstract
Prolyl hydroxylase [(EC 1.14.11.2; prolyl-glycyl peptide, 2-oxoglutarate dioxygenase (4-hydroxylating)] was electrophoresed on polyacrylamide gels and the enzyme in the gels was shown to bind [acetyl-3H]concanavalin A. The enzyme-lectin complex was dissociated by treating the gel with methyl -D-mannopyranoside, a sugar known to inhibit binding of concanavalin A to glycoproteins. Furthermore, prolyl hydroxylase activity was partially inhibited by concanavalin A when the enzyme was assayed in the absence of bovine serum albumin, a protein which enhances enzymic activity. The inhibition of enzyme activity was prevented by sugars known to react with concanavalin A. 1976.
