Theoretical molecular mass of the identified protein was based on the putative amino acid sequence including a signal sequence. Tryptic peptide fragments were identified by matching MS/MS spectra to Aspergillus, Talaromyces, and Hypocrea peptide sequences in the NCBI database. Cel5A and Cel7B peptides were identified by matching MALDI-TOF MS spectra with amino acid sequence translations of open reading frames in the T. cellulolyticus draft genome. aFragments were identified by both MS/MS spectra and MALDI-TOF MS spectra. GH, glycosyl hydrolase; MALDI-TOF MS, matrix-assisted laser desorption ionization time-of-flight mass spectrometry; MS/MS, tandem mass spectrometry.
