xylB encodes xylulokinase, which catalyzes the phosphorylation of xylulose to xylulose-5-phosphate, enabling its entry into the pentose phosphate pathway. Deletion of xylB blocks endogenous xylose assimilation and redirects xylulose derived from xylose toward secretion or conversion by heterologous enzymes, such as xylitol dehydrogenase [361].
