From: Improving l-serine formation by Escherichia coli by reduced uptake of produced l-serine
l-serine influx was assayed in E. coli ES and multigene deletion mutants. The data represent the means ± SDs from three measurements. ES represents the parental strain. ES-1: ES ΔsdaC; ES-12: ESΔsdaCΔcycA; ES-13: ESΔsdaCΔsstT; ES-14: ESΔsdaCΔtdcC; ES-123: ES ΔsdaCΔcycAΔsstT, ES-124: ESΔsdaCΔcycAΔtdcC; ES-134: ESΔsdaCΔsstTΔtdcC; ES-1234: ESΔsdaCΔcycAΔsstTΔtdcC
