Non-viral sialidases. Sialidases or neuraminidases function to bind and hydrolyze terminal sialic acid residues from various glycoconjugates, they play vital roles in pathogenesis, bacterial nutrition and cellular interactions. They have a six-bladed, beta-propeller fold with the non-viral sialidases containing 2-5 Asp-box motifs (most commonly Ser/Thr-X-Asp-[X]-Gly-X-Thr- Trp/Phe). This CD includes eubacterial and eukaryotic sialidases.

pneumococcal surface protein A. The pneumococcal surface protein proteins, found in Streptococcus pneumoniae, are repetitive, with patterns of localized high sequence identity across pairs of proteins given different specific names that recombination may be presumed. This protein, PspA, has an N-terminal region that lacks a cross-wall-targeting YSIRK type extended signal peptide, in contrast to the closely related choline-binding protein CbpA which has a similar C-terminus but a YSIRK-containing region at the N-terminus.

pneumococcal surface protein PspC, choline-binding form. The pneumococcal surface protein PspC, as described in Streptococcus pneumoniae, is a repetitive and highly variable protein, recognized by a conserved N-terminal domain and also by genomic location. This form, subgroup 1, has variable numbers of a choline-binding repeat in the C-terminal region, and is also known as choline-binding protein A. The other form, subgroup 2, is anchored covalently after cleavage by sortase at a C-terminal LPXTG site.
