Analyses of the F(420)s present in Methanococcus jannaschii have shown that these cells contain a series of gamma-glutamyl-linked F(420)s capped with a single, terminal alpha-linked L-glutamate. The predominant form of F(420) was designated as alpha-F(420)-3 and represented 86% of the F(420)s in these cells. Analyses of Methanosarcina thermophila, Methanosarcina barkeri, Methanobacterium thermoautotrophicum, Archaeoglobus fulgidus, and Mycobacterium smegmatis showed that they contained only gamma-glutamyl-linked F(420)s.
对詹氏甲烷球菌中存在的F(420)的分析表明,这些细胞含有一系列由单个末端α-连接的L-谷氨酸封端的γ-谷氨酰连接的F(420)。F(420)的主要形式被指定为α-F(420)-3,占这些细胞中F(420)的86%。对嗜热甲烷八叠球菌、巴氏甲烷八叠球菌、嗜热自养甲烷杆菌、嗜热栖热菌和耻垢分枝杆菌的分析表明,它们仅含有γ-谷氨酰连接的F(420)。
