The crystal structure of banyan peroxidase purified from the latex of Ficus benghalensis has been solved at 1.67 Å resolution by single-wavelength anomalous diffraction phasing. The refined structure includes 306 amino acid residues, a heme and two calcium ions. The protein belongs to class III peroxidases and is the first one from plant latex. Extensive glycosylation was observed with N-linked glycans attached to seven asparagine residues. The enzyme is stable with respect to a wide pH range, temperature, chemical denaturants and organic solvents, probably as a result of its high glycosylation. An unexpected post-translational modification of Asp290 was identified as succinimide moiety. Kinetic parameters of banyan peroxidase have been determined using various hydrogen donor substrates and hydrogen peroxide.
