Lac Operon - Concept, Diagram, Notes, Gene Regulation

Lac Operon - an overview | ScienceDirect Topics The lac operon consists of three coding regions in tandem, lacZ, lacY, and lacA. The lacZ gene encodes β-galactosidase, which degrades lactose. The lacY gene product, lactose permease, transports lactose into the cell, and the lacA gene product, lactose acetylase, has an unknown and not usually necessary function.

Lac Operon: Mechanism and Regulation - Microbe Online The lac operon consists of a promoter (P) and operator (O) region followed by three structural genes lacZ, lacY, and lacA in the downstream.
