FIG. 1.

Protein sequences predicted from nucleic acid sequences of C. subvermispora oxalate oxidase allelic isoforms OxoX-C and OxoX-G. Peptide sequences of the purified oxalate oxidase obtained using quadrupole time-of-flight mass spectrometry are aligned above the protein sequences. Conserved, highly conservatively substituted, and moderately conservatively substituted amino acids are highlighted with asterisks, colons, and stops, respectively. Putative signal peptide sequences are underlined. The duplicated cupin motifs are boxed and consecutively labeled 1a, 1b, 2a, and 2b in italics. Putative N-glycosylation sites are highlighted in boldface type.
