Abstract: | Summary Aldolase activity in the cell-free extracts of two dermatophytes,T. mentagrophytes andT. rubrum, was investigated. The kinetics of the enzyme and the effects of metal ions and metal-binders are also reported. The enzyme was more active inT. mentagrophytes than inT. rubrum. The optimum pH for the enzyme action was 7.2 and it was completely inactivated at 60° C. Cobalt and magnesium ions and cysteine activated the enzyme. Inhibition caused by EDTA and o-phenanthroline was partially reversed by cobalt ions. The dermatophyte aldolase resembles bacterial aldolase in its properties. |
