3.A.1.1.56
Uptake transport system for L-arabinose and D-xylose, XacGHIJK (Johnsen et al. 2019). The system has a receptor, two 6 TMS membrane proteins and two ATPases.  xacGHIJK is upregulated by growth in the presence of either D-xylose or L-arabinose, mediated by the transcriptional regulator, XacR, the general regulator of xac catabolic genes (Johnsen et al. 2019).
