Kinetic gating mechanism of DNA damage recognition by Rad4/XPC
The xeroderma pigmentosum C (XPC) complex initiates nucleotide excision repair by recognizing DNA lesions before recruiting downstream factors. How XPC detects structurally diverse lesions embedded within normal DNA is unknown. Here we present a crystal structure that captures the yeast XPC orthologue (Rad4) on a single register of undamaged DNA. The structure shows that a disulphide-tethered R...
متن کاملSingle-molecule recognition imaging microscopy.
Atomic force microscopy is a powerful and widely used imaging technique that can visualize single molecules and follow processes at the single-molecule level both in air and in solution. For maximum usefulness in biological applications, atomic force microscopy needs to be able to identify specific types of molecules in an image, much as fluorescent tags do for optical microscopy. The results p...
متن کاملDesigning a Single-Molecule Biophysics Tool for Characterising DNA Damage for Techniques that Kill Infectious Pathogens Through DNA Damage Effects.
Antibiotics such as the quinolones and fluoroquinolones kill bacterial pathogens ultimately through DNA damage. They target the essential type IIA topoisomerases in bacteria by stabilising the normally transient double-strand break state which is created to modify the supercoiling state of the DNA. Here we discuss the development of these antibiotics and their method of action. Existing methods...
متن کاملSingle-molecule imaging reveals the mechanism of Exo1 regulation by single-stranded DNA binding proteins.
Exonuclease 1 (Exo1) is a 5'→3' exonuclease and 5'-flap endonuclease that plays a critical role in multiple eukaryotic DNA repair pathways. Exo1 processing at DNA nicks and double-strand breaks creates long stretches of single-stranded DNA, which are rapidly bound by replication protein A (RPA) and other single-stranded DNA binding proteins (SSBs). Here, we use single-molecule fluorescence imag...
متن کاملTwist-open mechanism of DNA damage recognition by the Rad4/XPC nucleotide excision repair complex.
DNA damage repair starts with the recognition of damaged sites from predominantly normal DNA. In eukaryotes, diverse DNA lesions from environmental sources are recognized by the xeroderma pigmentosum C (XPC) nucleotide excision repair complex. Studies of Rad4 (radiation-sensitive 4; yeast XPC ortholog) showed that Rad4 "opens" up damaged DNA by inserting a β-hairpin into the duplex and flipping...
