The typical bacterial pathway of xylose catabolism involves uptake, isomerization to xylulose, and phosphorylation to xylulose-5-phosphate, an intermediate of the pentose phosphate pathway. C. glutamicum possesses xylulokinase XylB, but lacks xylose isomerase XylA [109]. Heterologous expression of xylA from R coli was sufficient to enable growth with xylose as the sole carbon source [109]. Combined overexpression of xylA from Xanthomonas campestris and the endogenous xylB gene led to the fastest growth with xylose reported to date [136]. Expression 

A model L-lysine producer provided with these genes produced L-lysine from D-galacturonic acid and D-glucuronic acid, but grew poorly [145].
