Polyphenol oxidase: Difference between revisions

In walnut (''[[Juglans regia]]''), two different genes (''jr''PPO1 and ''jr''PPO2) encoding [[polyphenol oxidase]]<nowiki/>s have been identified. The two [[Isozyme|isoenzyme]]<nowiki/>s prefer different [[Substrate (chemistry)|substrate]]<nowiki/>s, as ''jr''PPO1 shows a higher activity towards [[monophenol]]<nowiki/>s, whereas ''jr''PPO2 is more active towards [[diphenol]]<nowiki/>s.<ref>{{Cite journal|last=Panis|first=Felix|last2=Kampatsikas|first2=Ioannis|last3=Bijelic|first3=Aleksandar|last4=Rompel|first4=Annette|date=|title=Conversion of walnut tyrosinase into a catechol oxidase by site directed mutagenesis|url=http://www.nature.com/articles/s41598-020-57671-x|journal=Scientific Reports|language=en|volume=10|issue=1|pages=1659|doi=10.1038/s41598-020-57671-x|issn=2045-2322|pmc=PMC6997208|pmid=32015350}}</ref><ref>{{Cite journal|last=Panis|first=Felix|last2=Rompel|first2=Annette|date=|title=Identification of the amino acid position controlling the different enzymatic activities in walnut tyrosinase isoenzymes (jrPPO1 and jrPPO2)|url=http://www.nature.com/articles/s41598-020-67415-6|journal=Scientific Reports|language=en|volume=10|issue=1|pages=10813|doi=10.1038/s41598-020-67415-6|issn=2045-2322|pmc=PMC7331820|pmid=32616720}}</ref>
