Construction and characterization of Escherichia coli disruptants defective in the yaeM gene

Biosci Biotechnol Biochem. 1999 Apr;63(4):776-8. doi: 10.1271/bbb.63.776.

Abstract

Escherichia coli disruptants defective in the yaeM gene, which is located at 4.2 min on the chromosome map, were constructed and characterized. The disruptants showed auxotrophy for 2-C-methylerythritol, a free alcohol of 2-C-methyl-D-erythritol 4-phosphate that is a biosynthetic precursor in the nonmevalonate pathway. This result clearly shows that the yaeM gene is indeed involved in this pathway in E. coli.
