Copper radical oxidases: galactose oxidase, glyoxal oxidase, and beyond!
The copper radical oxidases (CROs) are an evolutionary and functionally diverse group of enzymes established by the historically significant galactose 6-oxidase and glyoxal oxidase from fungi. Inducted in 2013, CROs now constitute Auxiliary Activity Family 5 (AA5) in the Carbohydrate-Active Enzymes (CAZy) classification. CROs catalyse the two-electron oxidation of their substrates using oxygen as the final electron acceptor and are particularly distinguished by a cross-linked tyrosine-cysteine co-factor that is integral to radical stabilization. Recently, there has been a significant increase in the biochemically and structurally characterized CROs, which has revealed an expanded natural diversity of catalytic activities in the family. This review provides a brief historical introduction to CRO biochemistry and structural biology as a foundation for an update on current advances in CRO enzymology, biotechnology, and biology across kingdoms of life.
期刊介绍：
Essays in Biochemistry publishes short, digestible reviews from experts highlighting recent key topics in biochemistry and the molecular biosciences. Written to be accessible for those not yet immersed in the subject, each article is an up-to-date, self-contained summary of the topic.
Bridging the gap between the latest research and established textbooks, Essays in Biochemistry will tell you what you need to know to begin exploring the field, as each article includes the top take-home messages as summary points.
Each issue of the journal is guest edited by a key opinion leader in the area, and whether you are continuing your studies or moving into a new research area, the Journal gives a complete picture in one place.
Essays in Biochemistry is proud to publish Understanding Biochemistry, an essential online resource for post-16 students, teachers and undergraduates. Providing up-to-date overviews of key concepts in biochemistry and the molecular biosciences, the Understanding Biochemistry issues of Essays in Biochemistry are published annually in October.
