Reversion and interallelic complementation at four urease loci in Neurospora crassa.
Analysis of heat stability of urease in extracts of 24 revertants, six for each of four ure loci, revealed that at least one revertant for each locus had a heat stability about one-third that of wild type. Similar results were obtained with urease formed by interallelic complementation at the ure-2 and ure-4 loci, but interallelic complementation at the ure-1 and ure-3 loci produced insufficient urease activity for analysis. The data are interpreted to suggest, as a tentative model, a structural function for each of the four ure loci.
