Crosslinking proteins and chromosomes via uv 4. These enzymes are only required when that substrate is available, thus expression of the operons is typically induced only in the presence of the substrate. Often, these molecules act by binding to dna near the gene and helping or blocking the transcription enzyme, rna polymerase.
