A member of the amidohydrolase superfamily, BmulJ_04915 from Burkholderia multivorans, of unknown function was determined to hydrolyze a series of sugar lactones: L-fucono-1,4-lactone, D-arabino-1,4-lactone, L-xylono-1,4-lactone, D-lyxono-1,4-lactone, and L-galactono-1,4-lactone. The highest activity was shown for L-fucono-1,4-lactone with a k(cat) value of

The halophilic archaeon Haloferax volcanii utilizes l-rhamnose as a sole carbon and energy source. It is shown that l-rhamnose is taken up by an ABC transporter and is oxidatively degraded to pyruvate and l-lactate via the diketo-hydrolase pathway. The genes
