Composite

Part:BBa_K4032102

Designed by: Tsubasa Okada   Group: iGEM21_Gunma   (2021-09-30)


lacI+RBS+α-gal+double terminator

Contents:

・The lac promoter from BBa_R0010

・The RBS from BBa_B0034

・The α-galactosidase gene melA from E. coli (BBa_K4032000)

・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. For more information, UniProt EC:3.2.1.22.



Design

The lac promoter and the double terminator are added to BBa_K4032005, forming this part.

The lac promoter and the double terminator are from BBa_J04450.


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