Schematic summary of exogenous glycogen utilization in S. pneumoniae showing the degradation of glycogen (1), specific recognition and transport of the products (2–4), and processing of the internalized glycan products (5). The proteins putatively involved in processing the internalized glycans were proposed as the most likely candidates based on their predicted functions. The role of SP_0758, the MalT homolog, is putative. The putative transported products of SP_0758 are indicated as phosoph-sugars consistent with the normal function of a carbohydrate specific PTS. The yellow circles represent the nucleotide binding/ATPase component of the ABC transporter whose gene is apparently not present in the maltodextrin metabolon. Green linked hexagons represent the peptidoglycan layer to which SpuA is attached. The capsule is omitted for clarity.
