Five truncation mutants of chloroplast ATP synthasecsubunit from spin-ach (Spinacia oleracea) lacking 8, 12, 16, 20 or 60 N-terminal amino acids were generated by PCR by a mutagenesis method. The recombinantc genes were overexpressed inEscherichia coliand assembled withabsub-units into a native complex. The wild-type (WT)abcassembly i.e.abcWT exhibited high Mg 2+ -dependent and Ca 2+ -dependent ATP hydrolytic activity.

A homology search of the genome database of the filamentous fungus Trichoderma reeseiidentified a new T. reeseityrosinase gene tyr2, encoding a protein with a putative signal sequence. The gene was overexpressed in the native host under the strong cbh1 promoter, and the tyrosinase enzyme was secreted into the culture supernatant.
