4.2.1.141	additional information	the deletion mutant DELTAKDXD/KDAD of the 2-keto-3-deoxyarabinoate/xylonate dehydratase is no longer able to catabolize D-xylose or L-arabinose, suggesting the absence of the aldolase-dependent branch in Sulfolobus acidocaldarius. In the DELTAKDXD/KDAD mutant, no KDXD/KDAD activity is detected on the four different carbon and energy sources, confirming the absence of an alternative pathway/enzyme for KDX/KDA conversion under these conditions in Sulfolobus acidocaldarius strain MW001	-, 746849
