| Abstract: | Pyruvate dehydrogenase complex mutants of Aspergillus nidulans were obtained by ultraviolet treatment and enrichment procedures. Among 160 glycolytic mutants, 86 pyruvate dehydrogenase complex mutants (including some temperature-sensitive mutants) were found. In addition to genes pdhA and pdhB, which are described in previous studies, a third gene, pdhC, controlling the function of the enzyme complex, was identified. The three genes were not linked and were mapped in the following linkage groups: pdhA in group I, pdhB in group V, and pdhC in group VIII, where it was the first marker on the left arm. |
