Diazirine-based DNA photo-cross-linking probes for the study of protein-DNA interactions

(Figure Presented) Small modification, large effect: Diazirine can be installed quickly and simply in the major or minor groove of DNA for efficient photo-cross-linking to proteins (see picture). This method should be suitable for mapping out protein-DNA interactions, in particular those that may be sensitive to steric hindrance.

Photoaffinity palladium reagents for capture of protein-protein interactions

Protein-protein interactions (PPIs) are indispensable in almost all cellular processes. Probing of complex PPIs provides new insights into the biological system of interest and paves the way for the development of therapeutics. Herein, we report a strategy for the capture of protein-protein interactions using photoaffinity palladium reagents. First, the palladium-mediated reagent site specifically transferred a photoaffinity modified aryl group to the designated cysteine residue. Next, the photoaffinity group was activated by UV radiation to trap the proximal protein residue for the formation of a crosslink. This strategy was used to capture the PYL-ABA-PP2C interaction, which is at the core of the abscisic acid (ABA) signalling pathway. Our results indicated that this palladium-mediated strategy can serve as an alternative for incorporating an increasing number of diverse substrates for protein crosslinking through cysteine modifications and can be explored for use in mapping protein-peptide or protein-protein interaction surfaces and in trapping potential interacting partners.

The Thermal Decomposition of Diazirines: 3-(3-Methyldiazirin-3-yl)propan-1-ol and 3-(3-Methyldiazirin-3-yl)propanoic Acid

The thermolyses of 3-(3-methyldiazirin-3-yl)propan-1-ol (1) and 3-(3-methyldiazirin-3-yl)propanoic acid (2) have been studied in solution over the temperature range 96-125 deg C.The reactions are unimolecular and fit linear Arrhenius plots with k(1)=1013.85+/-0.69exp-1/RT>s-1 and k(2)=1012.38+/-0.43exp-1/RT>s-1.The major products are the alkenes derived from the corresponding carbenes MeC2.CH2CH2CH2OH (3) and MeC2.CH2CH2CO2H (4).The new rate data, taken together with previous work, tend to confirm that diazirine thermolysis involves ring opening to a "complex" followed either by nitrogen loss or by isomerization to a diazo compound.Whereas (1) gives no product of closure onto oxygen, the acid (2) affords about 5percent γ-valerolactone.
