REGULATION OF NEWLY EVOLVED ENZYMES II. THE EBG REPRESSOR

[摘要] The ebg (evolved β-galactosidase) regulatory locus has been mapped. The map order is argG - ebgA - ebgR - tolC - metC , and there is 1.6% recombination between ebgR and ebgA . Studies with ebgR-/ebgR+ merdiploids have shown that ebgR- is recessive, and it is concluded that the synthesis of ebg enzyme is under negative control.
