photoproduct

The final step is the rearrangement to the bicyclic photoproduct.

The initial photoproduct obtained from santonin is lumisantonin.

The mechanism of action varies from toxin to toxin, but is usually due to the production of a photoproduct.

This caused the conversion of OPN5 into a blue-absorbing photoproduct (470 nm), which was stable in the dark.

Spore photoproduct lyase provides another enzymatic pathway for repair of thymine photodimers.

The likely spectral overlap between pR and its own postulated N photoproduct complicates the determination of amounts of each that are present.

SplB - spore photoproduct lyase (DNA repair)

A first photoproduct called photorhodopsin forms within 200 femtoseconds after irradiation followed within picoseconds by a second one called bathorhodopsin with distorted all-trans bonds.

A Norrish type II reaction is the photochemical intramolecular abstraction of a γ-hydrogen (which is a hydrogen atom three carbon positions removed from the carbonyl group) by the excited carbonyl compound to produce a 1,4-biradical as a primary photoproduct (IUPAC definition).

Examples of radical SAM enzymes include spore photoproduct lyase, activases of pyruvate formate lyase and anaerobic sulfatases, lysine 2,3-aminomutase, and various enzymes of cofactor biosynthesis, peptide modification, metalloprotein cluster formation, tRNA modification, lipid metabolism, etc.
