New Catalytic Residues and Catalytic Mechanism of the RNase T1 Family [PDF]

open access: yesACS Bio & Med Chem Au
The ribonuclease T1 family, including RNase Po1 secreted by Pleurotus ostreatus, exhibits antitumor activity. Here, we resolved the Po1/guanosine-3'-monophosphate complex (3'GMP) structure at 1.75 Å. Structure comparison and fragment molecular orbital (FMO) calculation between the apo form and the Po1/3'GMP complex identified Phe38, Phe40, and Glu42 as

Catalytic mechanism of F1-ATPase

open access: yesBiochimica Et Biophysica Acta - Bioenergetics, 1997
The structure of the core catalytic unit of ATP synthase, alpha 3 beta 3 gamma, has been determined by X-ray crystallography, revealing a roughly symmetrical arrangement of alternating alpha and beta subunits around a central cavity in which helical portions of gamma are found.

Structural and Functional Basis of JAMM Deubiquitinating Enzymes in Disease

open access: yesBiomolecules, 2022
Deubiquitinating enzymes (DUBs) are a group of proteases that are important for maintaining cell homeostasis by regulating the balance between ubiquitination and deubiquitination.

Comparison of Biochemical Characteristics, Action Models, and Enzymatic Mechanisms of a Novel Exolytic and Two Endolytic Lyases with Mannuronate Preference

open access: yesMarine Drugs, 2021
Recent explorations of tool-like alginate lyases have been focused on their oligosaccharide-yielding properties and corresponding mechanisms, whereas most were reported as endo-type with α-L-guluronate (G) preference.

Evolution of a Catalytic Mechanism [PDF]

open access: yesMolecular Biology and Evolution, 2015
The means by which superfamilies of specialized enzymes arise by gene duplication and functional divergence are poorly understood. The escape from adaptive conflict hypothesis, which posits multiple copies of a gene encoding a primitive inefficient and highly promiscuous generalist ancestor, receives support from experiments showing that resurrected ...

Catalytic mechanisms for phosphotriesterases [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2013
Phosphotriesters are one class of highly toxic synthetic compounds known as organophosphates. Wide spread usage of organophosphates as insecticides as well as nerve agents has lead to numerous efforts to identify enzymes capable of detoxifying them. A wide array of enzymes has been found to have phosphotriesterase activity including phosphotriesterase (

Recent Advances and Promises in Nitrile Hydratase: From Mechanism to Industrial Applications

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Nitrile hydratase (NHase, EC 4.2.1.84) is one type of metalloenzyme participating in the biotransformation of nitriles into amides. Given its catalytic specificity in amide production and eco-friendliness, NHase has overwhelmed its chemical counterpart ...

A structure of substrate-bound Synaptojanin1 provides new insights in its mechanism and the effect of disease mutations

open access: yeseLife, 2020
Synaptojanin1 (Synj1) is a phosphoinositide phosphatase, important in clathrin uncoating during endocytosis of presynaptic vesicles. It was identified as a potential drug target for Alzheimer’s disease, Down syndrome, and TBC1D24-associated epilepsy ...

Recent Progress of Electrochemical Production of Hydrogen Peroxide by Two‐Electron Oxygen Reduction Reaction

open access: yesAdvanced Science, 2021
Shifting electrochemical oxygen reduction reaction (ORR) via two‐electron pathway becomes increasingly crucial as an alternative/green method for hydrogen peroxide (H2O2) generation. Here, the development of 2e− ORR catalysts in recent years is reviewed,
