Abstract
Clostridium sporogenes has been found to require L-leucine and L-valine for growth in a minimal medium, although valine can be replaced by isobutyrate and leucine by isovalerate. Cells grown in minimal media incorporated significant 14C from [14C]valine into leucine and from [14C]leucine into valine. Growth with [4,5-3H]leucine also resulted in the incorporation of 3H into valine. These results indicate that these bacteria can interconvert leucine and valine.
摘要
已发现生孢梭菌在基本培养基中生长需要L-亮氨酸和L-缬氨酸，不过缬氨酸可用异丁酸替代，亮氨酸可用异戊酸替代。在基本培养基中生长的细胞将[14C]缬氨酸中的大量14C掺入亮氨酸，并将[14C]亮氨酸中的14C掺入缬氨酸。用[4,5-3H]亮氨酸培养也导致3H掺入缬氨酸。这些结果表明这些细菌能够使亮氨酸和缬氨酸相互转化。
