title: [Soluble and semisoluble lectins from mollicutes and their possible functions].
abstract: When studying mollicute lectins it was established that Acholeplasma laidlawii PG-8 synthesizes two half-soluble lectins one of which is specific to N-acetyl-D-glucosamine, and the other--to D-glucosamine.HCl; phytopathogenic strain A. laidlawii var. granulum 118 produced 4 lectins one of which is soluble and specific in respect to fructose-1.6-diphosphate, the rest three lectins are half-soluble and specific to one of the sugars--D-galactosamine.HCl, rafinose and D-glucosamine.HCl. In Mycoplasma pneumoniae FH all the four lectins found in the culture liquid have been classified as half-soluble, specific to one of carbohydrates--D-galactosamine.HCl, talose, N-acetyl-neuramine acid and D-glucose; M. capricolum Cal. Kid. synthesizes four lectins; two of them being defined as soluble (one of the lectins is, respectively, specific to talose and D-glucosamine.HCl, two others, as half-soluble, specific to one of sugars--rafinose or D-glucose. The results obtained permit a conclusion to be made that the half-soluble lectins of mollicutes, on the one hand, are the factors of adhesion on the corresponding organs of macroorganism and, on the other hand take part in the transport of substances from without into the microorganism cell. Soluble lectins determine pathogenicity of mollicutes and form with half-soluble lectins a single chain to providing the mycoplasma cells with nutrients and to protect them from the action of the macroorganism immune system.
