Cover for Acta Chimica Sinica vol 70 nº 20 based on paper by Zhang Liang, Yu Miao, He Chuan. Mouse Tet1 Protein can Oxidize 5mC to 5hmC and 5caC on Single-stranded DNA. The paper shows that Tet proteins can oxidize 5-methylcytosine (5mC) to 5-methylhydroxicytosine (5hmC) and 5hmC to 5-Carboxylcytosine (5caC) on single-stranded DNA as well […]

Molecular biology: RNA modification does a regulatory two-step. The m6A structural modification of RNA regulates gene expression. It has now been found to mediate an unusual control mechanism: by altering the structure of RNA, m6A allows a regulatory protein to bind to that RNA.

Thiol-group oxidation of active and allosteric cysteines is a widespread regulatory posttranslational protein modification. Pathogenic bacteria, including Pseudomonas aeruginosa and Staphylococcus aureus, use regulatory cysteine oxidation to respond to and overcome reactive oxygen species (ROS) encountered in the host environment.

Carbonic anhydrases catalyze the reversible hydration of CO2. Since the discovery of this zinc (Zn) metalloenzyme in erythrocytes over 65 years ago, carbonic anhydrase has not only been found in virtually all mammalian tissues but is also abundant in plants and green unicellular algae. The enzyme is important to many eukaryotic physiological processes such as […]
Human thymine DNA glycosylase (hTDG) efficiently excises 5-carboxylcytosine (5caC), a key oxidation product of 5-methylcytosine in genomic DNA, in a recently discovered cytosine demethylation pathway. We present here the crystal structures of the hTDG catalytic domain in complex with duplex DNA containing either 5caC or a fluorinated analog. These structures, together with biochemical and computational […]
