PG - 2790-2 AB - D-Alanine-D-alanine ligase (Ddl) and its mutants maintain the biosynthesis of peptidoglycan, and the substrate specificity of Ddls partially affects the resistance mechanism of vancomycin-resistant enterococci. Through investigation of Ddls, Ddl from Thermotoga maritima ATCC 43589 showed novel characteristics, vis. thermostability up to 90 degrees C and broad substrate specificity toward 15 D-amino acids, particularly D-alanine, D-cysteine, and D-serine, in that order.
