Summary
RhaA also has L- lyxose isomerase activity and is needed for growth on L-lyxose (Badia, 1991). [More information is available at EcoGene: EG11867]. L-rhamnose isomerase catalyzes the first step in the utilization of the deoxyhexose sugar rhamnose. [More information is available at EcoCyc: EG11867].
