Domain analysis of protein P30 in Mycoplasma pneumoniae cytadherence and gliding motility.
The cell wall-less prokaryote Mycoplasma pneumoniae causes bronchitis and atypical pneumonia in humans. Mycoplasma attachment and gliding motility are required for colonization of the respiratory epithelium and are mediated largely by a differentiated terminal organelle. P30 is a membrane protein at the distal end of the terminal organelle and is required for cytadherence and gliding motility, ...
متن کاملMutant analysis reveals a specific requirement for protein P30 in Mycoplasma pneumoniae gliding motility.
The cell-wall-less prokaryote Mycoplasma pneumoniae, long considered among the smallest and simplest cells capable of self-replication, has a distinct cellular polarity characterized by the presence of a differentiated terminal organelle which functions in adherence to human respiratory epithelium, gliding motility, and cell division. Characterization of hemadsorption (HA)-negative mutants has ...
متن کاملP65 truncation impacts P30 dynamics during Mycoplasma pneumoniae gliding.
The cell wall-less prokaryote Mycoplasma pneumoniae is a major cause of community-acquired bronchitis and pneumonia in humans. Colonization is mediated largely by a differentiated terminal organelle, which is also the leading end in gliding motility. Cytadherence-associated proteins P30 and P65 appear to traffic concurrently to the distal end of developing terminal organelles. Here, truncation ...
متن کاملGliding motility of Mycoplasma pulmonis.
The gliding movements of freshly isolated Mycoplasma pulmonis cells were observed and measured. The motile cells had a characteristic appearance, an average speed of 0.4 to 0.7 micron/s, and a maximum speed of 1 micron/s.
متن کاملProtein kinase/phosphatase function correlates with gliding motility in Mycoplasma pneumoniae.
Mycoplasma pneumoniae exhibits a novel form of gliding motility that is mediated by the terminal organelle, a differentiated polar structure. Given that genes known to be involved in gliding in other organisms are absent in M. pneumoniae, random transposon mutagenesis was employed to generate mutants with gliding-deficient phenotypes. Transposon insertions in the only annotated Ser/Thr protein ...
