Twist and turn: a revised structural view on the unpaired bubble of class II CPD photolyase in complex with damaged DNA

IUCrJ, 2018
Cyclobutane pyrimidine dimer (CPD) photolyases harness the energy of blue light to repair UV-induced DNA CPDs. Upon binding, CPD photolyases cause the photodamage to flip out of the duplex DNA and into the catalytic site of the enzyme.

Structural basis of cyclobutane pyrimidine dimer recognition by UV-DDB in the nucleosome

Nature Communications
In mammalian global genomic nucleotide excision repair, UV-DDB plays a central role in recognizing DNA lesions, such as 6-4 photoproducts and cyclobutane pyrimidine dimers, within chromatin.

ASH1L histone methyltransferase regulates the handoff between damage recognition factors in global-genome nucleotide excision repair

Nature Communications, 2017
UV-induced mutagenic cyclobutane pyrimidine dimers on nucleosomal DNA are sensed by the damage recognition factors DDB2 and XPC via an unknown mechanism. Here, the authors show that the histone methyltransferase ASH1L regulates the DDB2 to XPC handoff by

1-(3-Mesityl-3-methylcyclobutyl)-2-phenoxyethanone

Acta Crystallographica Section E, 2010
In the title compound, C22H26O2, the cyclobutane ring is puckered, with a dihedral angle of 24.97 (9)° between the two C3 planes. In the crystal, intermolecular non-classical C—H...O interactions between the methylcyclobutyl ...

Kaemphenolide: a cyclobutane-bearing phenylpropanoid from Kaempferia galanga L. with nitric oxide inhibitory activity

Natural Products and Bioprospecting
An undescribed phenylpropanoid dimer featuring a rare cyclobutane ring was isolated from the rhizomes of Kaempferia galanga L., a medicinal plant traditionally used in Southeast Asia for its anti-inflammatory and therapeutic properties. Kaemphenolide (1),

Cycloreversion-enhanced toughness and degradability in mechanophore-embedded end-linked polymer networks

Nature Communications
Enhancing the toughness while achieving triggerable degradation in single-network polymer systems without modifying their inherent chemical composition or network architecture remains a significant challenge.

Essential oil-derived decomposable polymers via cycloaddition polymerization of silyl ether-linked phenylpropanoids

Nature Communications
Owing to increasing concerns regarding climate change, research concerning the use of plant biomass as a renewable carbon resource has become increasingly active. Phenylpropanoids, which are aromatic compounds derived from plants, offer renewable sources
