Involved in the biosynthesis of phenolic monoterpene natural product thymol which has a broad range of biological activities acting as antimicrobial compound, insecticide, antioxidant and pharmaceutical agent (Ref.1). Catalyzes probably the C3-hydroxylation of gamma-terpinene to produce thymol (Ref.1). Secondary metabolite biosynthesis; terpenoid biosynthesis. The monoterpenic phenol thymol is widely used as a fragrance and a flavoring ingredient in food and cosmetic industries (PubMed:29785774). Its derivatives have also several biological and pharmacological properties such as antimicrobial, antioxidant, anticarcinogenesis, anti-inflammatory and antispasmodic activities (PubMed:29785774, PubMed:29874939). Medical applications include the treatment of disorders affecting the respiratory, nervous, and cardiovascular systems (PubMed:29785774). It may also act as a growth enhancer and immunomodulator (PubMed:29785774). Thymol may also have antiviral activity toward COVID-19 by binding to the S1 receptor binding domain of the SARS-CoV-2 spike (S) glycoprotein (PubMed:32834111, PubMed:33855010). Belongs to the cytochrome P450 family.
