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 ...

Catalytic Mechanism of Cdc25

Biochemistry, 2002
Cdc25 is a dual-specificity phosphatase that catalyzes the activation of the cyclin-dependent kinases, thus causing initiation and progression of successive phases of the cell cycle. Although it is not significantly homologous in sequence or structure to other dual-specificity phosphatases, Cdc25 belongs to the class of well-studied cysteine ...

The Catalytic Mechanism of Human Transketolase

ChemPhysChem, 2019
AbstractWe have computationally determined the catalytic mechanism of human transketolase (hTK) using a cluster model approach and density functional theory calculations. We were able to determine all the relevant structures, bringing solid evidences to the proposed experimental mechanism, and to add important detail to the structure of the transition ...
