ABSTRACT
Genetic data suggest that the oligotrophic freshwater bacterium
Caulobacter crescentus
metabolizes
d
-xylose through a pathway yielding α-ketoglutarate, comparable to the recently described
l
-arabinose degradation pathway of
Azospirillum brasilense
. Enzymes of the
C. crescentus
pathway, including an NAD
+
-dependent xylose dehydrogenase, are encoded in the xylose-inducible
xylXABCD
operon (CC0823-CC0819).
