[Characteristic of extracellular lectin in Bacillus subtilis IMV B-7014]

The monosaccharide and fatty acid composition of water and organic phase of lectin was studied. It was established that extracellular lectin contains 15.0% of protein, 4.6% of carbohydrates, 1.0% of nucleic acids and 16.14% of lipids. The following monosaccharides were presented in the lectins: mannose, ribose, glucose and ramnose. It was established that both native lectin and its lipophylic fraction were composed of fatty acids from C15 to C19. During aggressive methanolysis anti-iso-C15 quantity was increased with a synchronous decrease of the content of all octadecanoic acid types.
