Nucleotide and protein sequence b-galactosidase Streptococcus mitis, obtaining procedure and its applications.

摘要

Nucleotide and protein sequence beta-galactosidase Streptococcus mitis, preparation process and their applications.; The present invention describes a beta-galactosidase protein unpublished of Streptococcus mitis having choline binding motifs in their structure and not inhibited in the presence of high glucose concentrations. Two purification procedures beta-galactosidases modified in a heterologous host (Escherichia coli) are also described.
