Hydrogen peroxide (H2O2) is continuously formed by the autoxidation of redox enzymes in
aerobic cells, and it also enters from the environment, where it can be generated both by …

The moderate stability of enzymes is one of the main drawbacks that hinder general
implementation of these interesting biocatalysts at industrial scale. An especially complex …

Human catalase is an heme-containing peroxisomal enzyme that breaks down hydrogen
peroxide to water and oxygen; it is implicated in ethanol metabolism, inflammation …

This review gives an overview about the structural organisation of different evolutionary lines
of all enzymes capable of efficient dismutation of hydrogen peroxide. Major potential …

Catalases from 16 different organisms including representatives from all three phylogenetic
clades were purified and characterized to provide a comparative picture of their respective …

Catalases are well studied enzymes that play critical roles in protecting cells against the
toxic effects of hydrogen peroxide. The ubiquity of the enzyme and the availability of …

Catalases continue to present a challenge and are an object of interest to the biochemist
despite more than 100 years of study. More than 120 sequences, seven crystal structures …

Multielectron redox reactions often require multicofactor metalloenzymes to facilitate
coupled electron and proton movement, but it is challenging to design artificial enzymes to …

The current techniques for X-ray-diffraction data collection from macromolecular crystals at
cryogenic temperatures are reviewed. The development of the experimental methods is …

This Handbook on Metalloproteins focuses on the available structural information of proteins
