STREPTOCOCCUS MITIS NUCLEOTIDE AND PROTEIN SEQUENCE OF STREPTOCOCCUS MITIS, OBTAINING PROCEDURE AND ITS APPLICATIONS.

摘要

Sequence of nucleotide and protein {be} -galactosidase of Streptococcus mitis, method of obtaining and its applications. # The present invention describes an unpublished protein {be} -galactosidase of Streptococcus mitis that has choline binding motifs in its structure and which does not It is inhibited in the presence of high concentrations of glucose. Two methods of purification of modified {be} -galactosidases in a heterologous host (Escherichia coli) are also described.
