Catabolite activator protein (CAP; also known as cAMP receptor protein, CRP) is a trans-acting transcriptional activator that exists as a homodimer in solution. Each subunit of CAP is composed of a ligand-binding domain at the N-terminus (CAP , residues 1–138) and a DNA-binding domain at the C-terminus (DBD, residues 139–209). Two cAMP (cyclic AMP) molecules bind dimeric CAP with negative WebEach Cap Analog is rigorously tested for contaminating nonspecific endonuclease, exonuclease, and RNase activity. Each is also assayed for the efficient synthesis of capped in vitro transcripts by using the cap analog in functional MEGAscript™ In Vitro transcription and Retic Lysate translation reactions.

WebJan 3, 2024 · During elongation, the transcription machinery needs to move histones out of the way every time it encounters a nucleosome. Transcription elongation occurs in a bubble of unwound DNA, where the RNA Polymerase uses one strand of DNA as a template to catalyze the synthesis of a new RNA strand in the 5′ to 3′ direction.

WebCAP binding site is centered at position −61. Upon binding, CAP induces a dramatic bend in the DNA (by ~80∞), wrapping DNA toward and. around the sides of the CAP dimer. CAP activates transcription by binding to CAP binding. site and interacting with the RNA polymerase α subunit C-terminal domain (αCTD).
