lacI+RBS+α-gal+double terminator

Contents:

・The lac promoter (from BBa_R0010)

・The RBS (from BBa_B0034)

・The E.coli alpha-galactosidase gene melA （）

・The double terminator (from BBa_B0015)

Usage and Biology

This enzyme catalyzes the hydrolysis of terminal, non-reducing alpha-D-galactose residues in alpha-D-galactosides, including galactose oligosaccharides, galactomannans and galactolipids. https://www.uniprot.org/uniprot/P06720

Design

The lac promoter and the double terminator are added to No part name specified with partinfo tag., forming this part.

The lac promoter and the double terminator are used from BBa_J04450.

This part was created by In-Fusion method using BBa_J04450 and melA from E.coli K-12 as an insert.
