Reactivation of Serratia marcescens Endonuclease NucSma(H89G) by Hydroxilamine [PDF]

Учёные записки Казанского университета: Серия Естественные науки, 2017
Serratia marcescens endonuclease is the most nonspecific nuclease known. This nuclease refers to enzymes that can cleave both DNA and RNA. The active site of this enzyme is characterized by the H–N–H motif, but more important functions have been shown ...

Enhancing the cellular uptake of Py–Im polyamides through next-generation aryl turns [PDF]

, 2012
Pyrrole–imidazole (Py–Im) hairpin polyamides are a class of programmable, sequence-specific DNA binding oligomers capable of disrupting protein–DNA interactions and modulating gene expression in living cells.

Oligoglyceric acid synthesis by autocondensation of glyceroyl thioester [PDF]

The autocondensation of the glyceroyl thioester, S-glyceroyl-ethane-thiol, yielded olioglyceric acid. The rates of autocondensation and hydrolysis of the thioester increased from pH 6.5 to pH 7.5 in 2,6-lutidine and imidazole buffers.

Proton transfer in histidine-tryptophan heterodimers embedded in helium droplets

, 2015
We used cold helium droplets as nano-scale reactors to form and ionize, by electron bombardment and charge transfer, aromatic amino acid heterodimers of histidine with tryptophan, methyl-tryptophan, and indole. The molecular interaction occurring through
