Protein

Biflaviolin synthase CYP158A2

Gene

cyp158a2

Organism
Streptomyces coelicolor (strain ATCC BAA-471 / A3(2) / M145)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyze oxidative C-C coupling reaction to polymerize flaviolin and form highly conjugated pigments which protect the soil bacterium from deleterious effects of UV irradiation (three isomers of biflaviolin and one triflaviolin).2 Publications

Catalytic activityi

2 flaviolin + NADPH + O2 = 3,3'-biflaviolin + NADP+ + 2 H2O.3 Publications
2 flaviolin + NADPH + O2 = 3,8'-biflaviolin + NADP+ + 2 H2O.3 Publications

Cofactori

heme3 Publications

Kineticsi

kcat is 1.4 min(-1) with flaviolin as substrate (at pH 7.5 and 37 degrees Celsius). kcat is 0.02 min(-1) with 2-hydroxy-1,4-naphthoquinone as substrate (at pH 7.5 and 25 degrees Celsius).2 Publications
