Figure Legend Snippet: Fermentation building (a), fermentation and drying processes of inoculated and spontaneous fermentations, and ambient temperatures (b). Positions a and b indicate the two parts of the fermentation box in (a). In (b), the positioning of the fermentation boxes F-A, F-B, and F-S during IF, IIF, and IIIF in positions P1-P3 is indicated on the y-axis. The horizontal axis indicates the time of fermentation (black line) and drying (grey line) and time when the fermenting pulp-bean mass in the centre of the box reached temperatures of 45–50 °C (bold black line). P = position; A min = minimal ambient temperature; A max = maximal ambient temperature.

Figure Legend Snippet: Temperatures in the fermenting pulp-bean mass of inoculated and spontaneous fermentations (a) and temperature distribution in the fermentation mass of IIF-A, representative for the nine studied fermentations (b). In part (a), temperatures measured in the centre of the box are shown for fermentation IF-A (bold bright grey line), IF-B (dashed bright grey line), IF-S (dotted bright grey line), IIF-A (bold dark grey line), IIF-B (dashed dark grey line), IIF-S (dotted dark grey line), IIIF-A (bold black line), IIIF-B (dashed black line), and IIIF-S (dotted black line). Ambient temperatures were measured in the fermentation building during run I (thin bright grey line), run II (thin dark grey line), and run III (thin black line). Part (b) shows temperatures measured at nine positions in fermentation box IIA: bottom-centre (solid bright grey line), bottom-side (dashed bright grey line), bottom-corner (dotted bright grey line), centre-centre (solid dark grey line), centre-side (dashed dark grey line), centre-corner (dotted dark grey line), top-centre (solid black line), top-side (dashed black line), and top-corner (dotted black line). 1–2 values deviated due to cold air being mixed with the pulp-bean mass and these were deleted to provide a clearer indication of temperature trends.

The two arms of N-glycan processing—complex N-glycan (top) and high-mannose N-glycan (bottom)—are shown as graphical representations and converge at ABC NG . Glycosidases are colour-coded according to their known or predicted activities: sialidase (purple), β-galactosidase (yellow), β-hexosaminidase (blue) and α-mannosidase (green). StrH is shown as a multimodular complex as it contains two catalytic domains [ 53 ]. NanA, BgaA, StrH and EndoD are extracellular and all bear LPXTG cell wall anchoring motifs. Complex N-glycan is sequentially depolymerized by NanA, BgaA and StrH [ 18 ], resulting in Man 3 GlcNAc 2 , which is then released from the glycoconjugate by EndoD [ 20 ]. High-mannose N-glycan is acted on by SpGH92, to produce Man 5 GlcNAc 2 , and is then released from the glycoconjugate by EndoD. Both Man 3 GlcNAc and Man 5 GlcNAc are transported by ABC NG into the cytoplasm, where further depolymerization is carried out by SpGH125 and SpGH38. Dedicated ABC and PTS transporters import the monosaccharides released by NanA, BgaA, StrH and SpGH92 [ 51 ]. The proposed architecture of ABC NG is shown inset.

Organization and conservation of a Carbohydrate Processing Locus (CPL) and other accessory proteins predicted to be associated with N-glycan processing. Genetic organization of a CPL and other accessory ORFs present in strains of S . pneumoniae whose protein products are putatively associated with N-glycan processing. The CPL consists of a characterized α-(1,6)-mannosidase (SpGH125) [ 21 ], two putative α-mannosidases (SpGH38 and SpGH92), a predicted α-fucosidase (GH29), a putative sugar kinase (ROK) and a known exo -β-hexosaminidase (SpGH20C) [ 28 ]. Other conserved proteins predicted to be associated with N-glycan processing include a characterized endo-β-N-acetylglucosaminidase (SpGH85 or EndoD) that is active on the core of N-linked glycans [ 24 ] and an ABC transporter (ABC NG ) that consists of a predicted solute binding protein (NgtS) and two putative permeases (NgtP1 and NgtP2). Locus tags shown underneath ORFs relate to the TIGR4 genome; black bars underneath ORFS indicate genes that are predicted to be co-transcribed. For the majority of the ORFs, coloring corresponds to the type of configured sugar acted on by the hydrolase: fucose (red), glucose (blue) and mannose (green).](https://storage.googleapis.com/bioz_article_images/PMC5215778/ppat.1006090.g001.jpg)
