arfI encoded the 57.7-kDa subunit of Cytophaga xylanolytica arabinofuranosidase I (ArfI). arfII encoded a 59.2-kDa subunit of ArfII. Products of both cloned genes liberated arabinose from arabinan and arabinoxylan. The deduced amino acid sequences of ArfI and ArfII revealed numerous regions that were identical to each other and to regions of homologous proteins from Bacteroides ovatus, Bacillus subtilis, and Clostridium stercorarium.
arfI编码解木聚糖噬纤维菌阿拉伯呋喃糖苷酶I(ArfI)的57.7 kDa亚基。arfII编码ArfII的59.2 kDa亚基。两个克隆基因的产物都能从阿拉伯聚糖和阿拉伯木聚糖中释放出阿拉伯糖。ArfI和ArfII推导的氨基酸序列显示,它们有许多区域彼此相同,并且与卵形拟杆菌、枯草芽孢杆菌和粪栖梭菌同源蛋白的区域相同。
