Cytoplasmic helical structure associated with Acholeplasma laidlawii.

A distinct spiral protein structure was found in three species of Acholeplasma, but was not found in the Mycoplasma species studied. The spirals, which are 14 nm in width and of variable length from 50 to 300 nm, are formed by a helical arrangement of 7-nm subunits. A rosette-like structure 45 nm in diameter also composed of 7-nm subunits was found in close association with the spirals and may ...

Extracellular Vesicles Derived from Acholeplasma laidlawii PG8

Extracellular vesicle production is believed to be a ubiquitous process in bacteria, but the data on such a process in Mollicutes are absent. We report the isolation of ultramicroforms - extracellular vesicles from supernatants of Acholeplasma laidlawii PG8 (ubiquitous mycoplasma; the main contaminant of cell culture). Considering sizes, morphology, and ultrastructural organization, the ultrami...

Complete genome and proteome of Acholeplasma laidlawii.

We present the complete genome sequence and proteogenomic map for Acholeplasma laidlawii PG-8A (class Mollicutes, order Acholeplasmatales, family Acholeplasmataceae). The genome of A. laidlawii is represented by a single 1,496,992-bp circular chromosome with an average G+C content of 31 mol%. This is the longest genome among the Mollicutes with a known nucleotide sequence. It contains genes of ...

Polyethylene Glycol-Dependent Transfection of Acholeplasma laidlawii

Phenol-extracted DNA from mycoplasma virus L2 was able to transfect Acholeplasma laidlawii in the presence of polyethylene glycol. Transfection was sensitive to DNase and was most efficient with 36% (wt/vol) polyethylene glycol 8000 and cells in logarithmic growth. Virus production by the transfected cells was similar to that of the cells infected by intact virus. L2 DNA transfected A. laidlawi...

A cation/proton antiport activity in Acholeplasma laidlawii.

Sealed membrane vesicles of Acholeplasma laidlawii were obtained by controlled lysis of carotenoid-rich intact cells. An imposed delta pH was created by loading membrane vesicles or intact Acholeplasma laidlawii cells with 0.25 M NH4Cl and diluting them into 0.25 M choline chloride. The passive efflux of NH3 from the membrane vesicles or cells resulted in the creation of a delta pH (inside acid...
