Synechocystissp。PCC6803是一种蓝细菌，它拥有一个不寻常的基因（fusB），该基因编码一种与蛋白质合成延伸因子G （EF-G）具有很强同源性的蛋白质，尽管它与经典的stroperon没有联系。fusb基因是多余的，因为与其他细菌的stroperon编码的fusagenes相似的asnechocystis基因也存在（基于PCR和杂交结果）。没有证据表明在其他细菌中也存在真菌同源物。胞囊菌fusBgene在一些位置编码不寻常的氨基酸，这些氨基酸在其他原核生物的基因中是高度保守的。
Synechocystissp. PCC6803, a cyanobacterium, possesses an unusual gene (fusB) which encodes a protein with strong homology to protein synthesis elongation factor G (EF-G), although it is not linked to the classicalstroperon. ThefusBgene is redundant, since aSynechocystisgene similar tostroperon-encodedfusAgenes of other bacteria is also present (based on PCR and hybridization results). There is no evidence for the presence of afusBhomologue in other bacteria. TheSynechocystis fusBgene encodes unusual amino acids at some positions that are highly conserved infusAgenes of other prokaryotes.
