Fig. 1From: Cysteine degradation gene yhaM, encoding cysteine desulfidase, serves as a genetic engineering target to improve cysteine production in Escherichia coli YhaM confers cysteine resistance. E. coli MG1655 carrying vector (pSTV29), ydeD on plasmid (pSTV-ydeD5), and yhaM on plasmid (pSTV-yhaM7) were streaked on a M9 plate containing 4 mM cysteine and incubated at 37 °C for 2 daysBack to article page
