The Adh1-Cmallele and each gene in the Adh1-FCmduplication have been cloned and restriction-mapped. Of the Cmallele 6 kb was sequenced. A single amino acid substitution of aspartate for tyrosine at residue 52 accounts for the altered enzymatic properties of the Cmprotein. Comparison of the nucleotide sequence to that of Adh1-1F and Adh1-1S shows structural and restriction site polymorphisms in the 3′ flanking DNA. Cmlacks the insertion sequence present in 1F and 1S and contains a complex sequence composed of two direct repeats and an inverted repeat. The two genes of the duplication allele have similar restriction maps to Cmand each other.
