Descriptor proteínas represoras
Entry term(s) moléculas represoras
Scope note: Proteínas que se unen normalmente al locus operador de un operón, impidiendo así la transcripción de los genes estructurales. En la inducción enzimática, el sustrato de la enzima inducible se une a la proteína represora, lo que hace que esta se separe del operador y libera los genes estructurales para la transcripción. En la represión enzimática, el producto final de la secuencia enzimática se une a la proteína represora libre, el complejo que se produce se une entonces al operador e impide la transcripción de los genes estructurales.

Scope note: Proteins which maintain the transcriptional quiescence of specific GENES or OPERONS. Classical repressor proteins are DNA-binding proteins that are normally bound to the OPERATOR REGION of an operon, or the ENHANCER SEQUENCES of a gene until a signal occurs that causes their release.
