Both hybrid promoters can be repressed by the lac repressor and both can be derepressed with isopropyl-beta-D-thiogalactoside.
Both the " ilvGMEDA " and " ilvBNC " operons are derepressed during shortages of the branched-chain amino acids by the same mechanism that represses them.
A powerful method of overcoming the catabolite repression in the enzyme biosynthesis is a fed-batch culture in which glucose concentration in the culture liquid is kept low, where growth is restricted, and the enzyme biosynthesis is derepressed.
The tacI and the tacII promoters respectively direct transcription approximately 11 and 7 times more efficiently than the derepressed parental lac UV5 promoter and approximately 3 and 2 times more efficiently than the trp promoter in the absence of the trp repressor.
:: At the individual gene level, Rao et al . have reported hypomethylation and thus derepression of synaptophysin ( " SYP " ), the major synaptic vesicle protein-encoding gene, has been shown to be hypermethylated and thus repressed, and transcription factor " NF-?B ", which is involved in immune signaling, has been shown to be hypomethylated and thus derepressed ( Rao et al ., 2012 ).
