Investigation of putative active-site lysine residues in hydroxymethylbilane synthase. Preparation and characterization of mutants in which (a) Lys-55, (b) Lys-59 and (c) both Lys-55 and Lys-59 have been replaced by glutamine.

A new construct carrying the hemC gene was transformed into Escherichia coli, resulting in approx. 1000-fold over-expression of hydroxymethylbilane synthase (HMBS). This construct was used to generate HMBS in which (a) Lys-55, (b) Lys-59 and (c) both Lys-55 and Lys-59 were replaced by glutamine (K55...
