Porphyrin and Phthalocyanine Chemistry

Evidence is presented for the presence of a reversible, nucleotide-dependent oxalacetic carboxylase in a cell-free extract of N. corallina. This enzyme is dependent upon sulfhydryl groups for its activity. Inosine and guanosine nucleotides are more active than adenosine and uridine nucleotides, and evidence is presented which indicates that the latter two nucleotides can act indirectly by way of inosine nucleotides. The presence of nucleoside diphosphokinase in the extract is indicated.
