Abstract
A Myxococcus xanthus cytoplasmic bacterial tyrosine kinase, BtkA, showed phosphorylation activity in the presence of Exo. Phosphorylated BtkA was expressed late after starvation induction and early after glycerol induction. The btkA mutant was unable to complete maturation to heat- and sonication-resistant spores under both starvation- and glycerol-induced developmental conditions.
摘要
黄色粘球菌细胞质细菌酪氨酸激酶 BtkA 在 Exo 的存在下表现出磷酸化活性。饥饿诱导后和甘油诱导后早期表达磷酸化 BtkA。在饥饿和甘油诱导的发育条件下，btkA 突变体均无法完成成熟为耐热和超声抗性孢子的过程。
