Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

Advanced Functional Materials, EarlyView.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Mechanisms of catalytic RNA molecules

Biochemical Society Transactions, 2021
Ribozymes are folded catalytic RNA molecules that perform important biological functions. Since the discovery of the first RNA with catalytic activity in 1982, a large number of ribozymes have been reported. While most catalytic RNA molecules act alone, some RNA-based catalysts, such as RNase P, the ribosome, and the spliceosome, need protein ...

Catalytic mechanism of glycogen phosphorylase

Faraday Discussions, 1992
Proposals for the catalytic mechanism of glycogen phosphorylase based on crystallographic studies with the T-state form of the enzyme are reviewed in the light of new structural data from studies with the R-state enzyme. The observed position for a sulfate ion at the catalytic site and the crystallographic binding studies of glucose-1-P to the R-state ...
