Mussel adhesive proteins including special functional groups, such as dopamine and 3,4-dihydroxy-l-phenylalanine (DOPA), exhibit strong adhesion and have thus been used in numerous applications. As a novel dye adsorbent for wastewater treatment, this study examineed poly(vinyl alcohol) (PVA) nanofi...
Tyrosinase catalyzes the hydroxylation of l-tyrosine to 3,4-dihydroxyphenylalanine (l-DOPA), followed by the oxidation of l-DOPA to dopaquinone. Oxidative polymerization of several dopaquinone derivatives gives rise to melanin (Parvez et al., 2006). Thus substances that inhibit tyrosinase may be ...

such as tyrosinase (TYR), 4,5-dihydroxy-phenylala- nine (DOPA)-dioxygenase (DOD) and glucosyltransferases (GTs) have been identified in higher plants.1,8–10 It has been proposed that TYR converts tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA), which in turn is converted to betalami...

[8]. Typical catechol amino acid, 3,4-dihydroxyphenylalanine, is responsible for these adhesions [4], [9]. Consequently, various attempts have been made to prepare catechol functionalized polymers [10], [11], [12]. However, the sensitivity of catechol moiety to oxidation unveils less control...
