F-like pili specified by conjugative plasmids have been reported to contain phosphate which may be noncovalently incorporated into the pilus. Electron spectroscopic imaging was able to detect phosphate in the filamentous, single-stranded DNA phage f1, used as positive control, but could not detect phosphate in F-like pili. Thus, the phosphate in purified pili which has been reported is probably derived from contaminating cell envelope material.
据报道，由接合质粒指定的F样菌毛含有磷酸盐，其可能非共价结合到菌毛中。电子光谱成像能够在用作阳性对照的丝状单链DNA噬菌体f1中检测到磷酸盐，但在F样菌毛中无法检测到磷酸盐。因此，已报道的纯化菌毛中的磷酸盐可能来自污染的细胞膜材料。
