鼠伤寒沙门氏菌和大肠杆菌的粗提物与 [32P] 磷酸烯醇丙酮酸或 [γ32P]ATP 孵育产生的磷蛋白已使用十二烷基硫酸钠聚丙烯酰胺凝胶电泳和放射自显影技术进行了解析和检测。人们发现了简单的技术,可以区分含有酸不稳定或稳定磷酸氨基酸的磷蛋白以及 N1-P-组氨酸和 N3-P-组氨酸。研究发现磷蛋白主要由磷酸烯醇丙酮酸形成,但由于有效的磷酸交换,ATP 也导致主要磷酸烯醇丙酮酸依赖性磷蛋白的形成。这些蛋白质具有以下表观亚基分子量:65,000、65,000、62,000、48,000、40,000、33,000、25,000、20,000、14,000、13,000、9,000、8,000。检测到的主要 ATP 依赖性磷蛋白的表观亚基分子量为 75,000、46,000、30,000 和 15,000。检测到其他次要磷蛋白。磷酸烯醇丙酮酸对 48,000 和 25,000 MW 蛋白质的磷酸化独立于磷酸烯醇丙酮酸:糖磷酸转移酶系统 (PTS)。 PTS 磷蛋白被鉴定为酶 I(可溶性;MW = 65,000); IIN-乙酰氨基葡萄糖酶(膜结合;MW = 65,000); II 甘露醇酶(膜结合;MW = 62,000); III 果糖(可溶;MW = 40,000); III甘露糖(部分膜相关;MW = 33,000); III 葡萄糖(可溶性;MW = 20,000); III 葡萄糖醇(可溶;MW = 13-14,000); HPr(可溶;MW = 9,000); FPr(果糖诱导的 HPr 样蛋白(可溶性;MW = 8,000)。HPr 和 FPr 在组氨酰残基的 N-1 位点上被磷酸化,而所有其他蛋白似乎在组氨酰残基的 N-3 位点上被磷酸化。这些研究鉴定了一些以前未知的 PTS 蛋白,并显示了其他蛋白的磷酸化,这些蛋白虽然以前已知,但并未被证明是磷蛋白。
Phosphoproteins produced by the incubation of crude extracts of Salmonella typhimurium and Escherichia coli with either [32P]phosphoenolpyruvate or [γ32P]ATP have been resolved and detected using sodium dodecyl sulphate poly‐acrylamide gel electrophoresis and autoradiography. Simple techniques were found such that distinctions could be made between phosphoproteins containing acid‐labile or stable phosphoamino acids and between N1‐P‐histidine and N3‐P‐histidine. Phosphoproteins were found to be primarily formed from phosphoenolpyruvate, but because of an efficient phosphoexchange, ATP also led to the formation of the major phosphoenolpyruvate‐dependent phosphoproteins. These proteins had the following apparent subunit molecular weights: 65,000, 65,000, 62,000, 48,000, 40,000, 33,000, 25,000, 20,000, 14,000, 13,000, 9,000, 8,000. Major ATP‐dependent phosphoproteins were detected with apparent subunit molecular weights of 75,000, 46,000, 30,000, and 15,000. Other minor phosphoproteins were detected. The phosphorylation of the 48,000‐ and 25,000‐MW proteins by phos‐phoenolpyruvate was independent of the phosphoenolpyruvate:sugar phospho‐transferase system (PTS). The PTS phosphoproteins were identified as enzyme I (soluble; MW = 65,000); enzyme IIN‐acetylglucosamine (membrane bound; MW = 65,000); enzyme IImannitol (membrane bound; MW = 62,000); IIIfructose (soluble; MW = 40,000); IIImannose (partially membrane associated; MW = 33,000); IIIglucose (soluble; MW = 20,000); IIIglucitol (soluble; MW = 13‐14,000); HPr (soluble; MW = 9,000); FPr (fructose induced HPr‐like protein (soluble; MW = 8,000). HPr and FPr are phosphorylated on the N‐1 position of a histidyl residue while all the others appear to be phosphorylated on an N‐3 position of a histidyl residue. These studies identify some previously unknown proteins of the PTS and show the phosphorylation of others, which although previously known, had not been shown to be phosphoproteins.
