Abstract excerpt

Xc17L, a lactose-utilizing mutant of Xanthomonas campestris pv. campestris previously isolated by mutagenesis with nitrous acid, displays a level of beta-galactosidase 3.5-fold higher than that in the parental Xc17. In this study, the gene encoding the enzyme displaying a higher specific activity in Xc17L was inactivated by mini-Tn5 transposition. Sequencing revealed that the product (579 aa, 63.5 kDa) of this...
