摘要

After the demonstration that Stigmatella aurantiaca DW4 secretes an endo-N-acetyl-beta-D-glucosaminidase (ENGase), acting on the di-N-acetylchitobiosyl part of N-linked glycans (S. Bourgerie, Y. Karamanos, T. Grard, and R. Julien, J. Bacteriol. 176:6170-6174, 1994), an ENGase activity having the same substrate specificity was also found to be secreted during vegetative growth of Myxococcus xanthus DK1622. The activity decreased in mutants known to secrete less protein than the wild type (Exc +/-). During submerged development, the activity was produced in two steps: the first increase occurred during the aggregation phase, and the second one occurred much later, during spore formation. This production was lower in developmental mutants impairing cell-cell signaling, the late mutants (csg and dsg) being the most deficient. Finally, when sporulation was obtained either by starvation in liquid shake flask culture or by glycerol induction, the activity was produced exclusively by the wild-type cells during the maturation of the coat.

Julien，J。Bacteriol。176：6170-6174，1994），还发现了具有相同底物特异性的ENGase活性在粘球菌DK1622的营养生长过程中被分泌。在已知比野生型（Exc +/-）分泌更少蛋白质的突变体中，活性降低。在淹没发育过程中，活性是通过两个步骤产生的：第一个增加发生在聚集阶段，第二个增加发生在孢子形成之后。在损害细胞-细胞信号传导的发育突变体中这种产生较低，晚期突变体（csg和dsg）最缺乏。最终，当通过摇瓶培养中的饥饿或通过甘油诱导获得孢子形成时，在外壳成熟期间，活性仅由野生型细胞产生。
