2.A.7.5.3
Glucose:H+ symporter, GlcU (YxfA) (high specificity, low affinity) (Castro et al., 2009). The effect of glucose stress on metabolic adaptation of Lactococcus lactis revealed that glucose stress up-regulated organic acid transport but down-regulated amino acid transport, resulted in a decrease in nitrogen metabolism (Qi et al. 2020).
