The budding yeast Saccharomyces cerevisiae Sigma1278b contains the MPR1 gene encoding N-acetyltransferase, which detoxifies the L-proline analog L-azetidine-2-carboxylate (AZC). Of 131 yeasts tested, AZC acetyltransferase activity was detected in 17 strains of 41 strains that showed AZC resistance. Degenerate-PCR analysis revealed that two strains, i.e., Candida saitoana AKU4533 and Wickerhamia fluorescens AKU4722, contained a DNA fragment highly homologous to MPR1. This indicates that AZC acetyltransferases are widely distributed in yeasts.
