Galactoside

C: The lactose operon of E.coli consists of three genes: lacZ encodes β-galactosidase, lacY encodes galactosidepermease which carries out lactose transport to the cell, lacA encodes galactoside-transacetylase. Lac operon is under the control of LacI (repressor), which is ...

... z gene 2) y gene, Lac y 3) a gene or Lac a Lac Z encodes for beta-galactosidase that is a lactase: cleaves lactose (the sugar). Lac y encodes for Galactoside permease that promotes the entry of lactose into the cell. lac a encodes for transacetylase, that adds an acetyl group to the lactose molecule ...
