  1. aLT, locus tag annotated as Pjdr2_#### abbreviated to consist only of the numeric portion, ####. Surface anchored proteins directly involved in the utilization of xylan, barley β-glucan and starch are denoted in bold
  2. bDomain predictions result from analysis of the proteins in the CCD (Conserved Domain Database) with an Expect Value threshold set to the default of 0.010 and increased to 0.10 to detect more divergent domains in unaccounted for regions or, as in some cases directly through the pfam database. Domain abbreviations are defined in order of appearance. CBM, Carbohydrate binding module; GH, Glycoside hydrolase; SLH, Surface layer homology domain; FN3, Fibronectin type 3 domain; DUF, Domain of unknown function; CF, Coagulation factor 5/8 C-terminal domain; RBT, Ricin-type beta-trefoil; RHB, Right handed beta helix; BIG, Bacterial Ig-like domain; PL, Pectate lyase; CCT, Chitobiase/beta-hexosaminidase C-terminal domain in the early set domain superfamily; PHP, Polymerase and histidinol phosphatase domain; AL, Alginate lyase; HP, Heparinase; NVS, Non-viral sialidases; GAG, Glycosaminoglycan polysaccharide lyase family; KCH, Galactose oxidase central domain; CLD, Cadherin-like beta sandwich domain; AMY, Alpha amylase catalytic domain family; ESD, Early set domain; CPRD, Carboxypeptidase regulatory-like domain; PBX Putative bacterial xylanases
  3. cFor any given domain an abbreviation is provided as defined under superscript (b), with numbers preceding the abbreviation indicating the number of consecutive occurrences greater than one (> 1) of the domain and numbers following the abbreviation indicating the specific family of the detected domain, if any
  4. dIn each modular protein the domain used to establish the “putative function” (sixth column) is underlined
  5. eAnnotated in the CAZy database as a GH115
  6. fSecretion was deduced by detection of a signal peptide using the Signal-P server
  7. gMolecular weight (MW) and isoelectric point (pI) predictions were obtained through the ProtParam tool available through the ExPASy web server
  8. hPutative function is based either on the predicted function from domain assignment or a justification for assignment as a protein that is involved with sugar manipulations
