Involved in the degradation of cineol (eucalyptol). Catalyzes the initial hydroxylation of cineole exclusively at the pro-R carbon to give the (S)-6beta-hydroxycineole. Cineole is the natural substrate of CinA. 1,8-cineole + O2 + reduced [flavodoxin] = 2-endo-hydroxy-1,8-cineole + H(+) + H2O + oxidized [flavodoxin] Terpene metabolism; 1,8-cineol degradation. Homodimer. It lacks the conserved threonine believed to be involved in dioxygen activation and instead contains an asparagine at position 242. It is the first isolated P450 using the flavoprotein cindoxin (CinC) as its natural redox partner (PubMed:12016226). Belongs to the cytochrome P450 family.
