C1. attributive, designating the genetic locus and genes associated with the ability of a bacterium to metabolize lactose, esp. in lac operon (see Compounds 2). Also in objective compounds, as lac operator, lac repressor.

1947 J. Lederberg in Genetics 32 517 The interaction of the Lac and V segregations is perhaps the most critical datum with which a genetic system for E. coli can be formulated.

1953 Proc. National Acad. Sci. U.S.A. 39 425 It is possible that the aberrant behavior of the Lac locus may be due to a linkage of Lac with the original biotin requirement.

1983 Irish Jrnl. Food Sci. & Technol. 7 52 The precise biochemical events controlled by plasmid encoded lac genes have been established in only a few strains [of streptococci].

1997 Biochemist Dec. 30/2 I have written a demonstration page..which examines the interactions between the lac repressor (a protein) and the lac operator (a DNA sequence).

2007 Sci. Amer. (U.K. ed.) Jan. 38/2 When lactose concentration rises above a certain threshold, the Lac complex lets go of the DNA template, allowing transcription of the genes to commence.
