[The amino acid and monosaccharide composition of the extracellular sialo-specific lectins in bacteria of the genus Bacillus]. 
Chemical composition of extracellular sialo-specific lectins of Bacillus genus bacteria has been studied.  It is shown that these biopolymers are glycoproteins distinguished by the quantitative and qualitative composition of proteins and hydrocarbons.  It is established that the given bacteria can synthesize one or two extracellular lectins one of which represents N-asparagine-bound glycoprotein, while another one belongs to O-serine/threonine-bound glycoproteins.
