    Notes: Summary A gene library with DNA of Staphylococcus hyicus subsp. hyicus was established in S. carnosus by using the plasmid vector pCT20. Two clones of S. carnosus were isolated which were able to ferment d-ribose. The two hybrid plasmids (pRib 1) and (pRib 2) were isolated and characterized. They contained inserted DNA fragments of S. hyicus subsp. hyicus with sizes of 10.2 and 8.2 kb, respectively. d-Ribose uptake and enzyme activities were studied. All strains tested [S. hyicus subsp. hyicus, S. carnosus (wild type) and the two S. carnosus clones] possessed an inducible uptake system for d-ribose. S. hyicus subsp. hyicus possessed in addition enzyme activities of d-ribokinase and d-ribose-5-P isomerase. None of these enzyme activities could be detected in S. carnosus (wildtype). Only in the S. carnosus clones containing (pRib 1) or (pRib 2) could a d-ribokinase activity be demonstrated, indicating that the gene for d-ribokinase of S. hyicus subsp. hyicus was cloned in S. carnosus.
