Protein turnover occurs during differentiation of Azotobacter vinelandii 12837 to the extent of 50% during encystment and 7% during germination. The addition of rifampin at the initiation of encystment prevents encystment and inhibits turnover. In germinating cysts, protein turnover is essential owing to an apparent lack of certain amino acid biosynthetic enzymes. The capacity to synthesize sulfur-containing amino acids from inorganic precursors is regained about halfway through the germination process.
在棕色固氮菌12837分化过程中会发生蛋白质周转，在形成孢囊期间周转程度达50%，在萌发期间为7%。在形成孢囊开始时添加利福平可阻止孢囊形成并抑制周转。在萌发的孢囊中，由于明显缺乏某些氨基酸生物合成酶，蛋白质周转至关重要。从无机前体合成含硫氨基酸的能力在萌发过程大约进行到一半时恢复。
