L-(+)-Lyxose
Based on 1 Customer Validation
L-(+)-Lyxose is an aldopentose monosaccharide that acts as a competitive inhibitor of rhamnose permease and a substrate of rhamnose isomerase. L-(+)-Lyxose competes with L-rhamnose for transport and is isomerized to L-xylulose. L-(+)-Lyxose is completely metabolized via the L-rhamnose catabolic pathway by the mutant strain Escherichia coli JA125 carrying a mutant L-rhamnulokinase. L-(+)-Lyxose can be used for metabolism-related research.

Biological Activity
Description
In Vitro
L-(+)-Lyxose supports the growth of mutant Escherichia coli JA125, which carries a mutant rhamnulose kinase capable of efficiently phosphorylating L-xylulose and completing catabolism via the L-rhamnose pathway[1].
L-(+)-Lyxose is converted to L-xylulose by purified E. coli JA121 rhamnose isomerase, with a Km of 5 mM and a Vmax of 6.0 U/mg[1].
L-(+)-Lyxose (L-Lyxose) can be generated from L-xylulose catalyzed by immobilized L-rhamnose isomerase[2].
