Allelic Complementation in the First Gene for Histidine Biosynthesis in SACCHAROMYCES CEREVISIAE. II. Complementation Mapping of Mutants and a Subunit Model of the Enzyme

RESUMO

Sixty-two alleles of the histidine-1 (his1) gene were tested for complementation. The 44 complementing mutants fell into 31 complementation groups which were used to construct a complex complementation map with 18 complementation units. Cluster analysis of the complementation map by either visual inspection or the computer method of Gillie and Peto (1969) shows two very definite clusters.
