LacZ alpha

An alpha peptide chain encoded by a gene LacZ


Usage and Biology

The LacZ alpha gene is one of the structural genes present on the Lac Operon in Escherichia coli bacteria . When transcribed by RNA polymerase , the LacZ alpha gene codes for β-galactosidase , an enzyme responsible for the hydrolysis of β-galactosides (e.g. 2-Nitrophenyl β-D-galactopyranoside (ONPG) )

Characterize

LacZ alpha gene encodes the β-galactosidase, which could react with 2-Nitrophenyl β-D-galactopyranoside (ONPG) to generate orange color.
