  1. aAccession numbers along with protein information and glycosyl hydrolase (GH) family information was obtained from Pedant [23].
  2. bHypothetical molecular weight of the proteins.
  3. cQuantifying changes in protein abundance between samples from different time points was done using the spectral count method, yielding a semiquantitative analysis.
  4. dSignalP was used to predict secretion signals [23, 24].
  5. eSignalP as reported at [25].
