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.

BNR repeat-like domain. This family of proteins contains BNR-like repeats suggesting these proteins may act as sialidases.

Neuraminidase (sialidase) [Carbohydrate transport and metabolism, Cell wall/membrane/envelope biogenesis].

N-terminal domain of BNR-repeat neuraminidase. This domain is usually found at the N-terminus of the BNR-repeat neuraminidase protein family.

Sortilin, neurotensin receptor 3,. Sortilin, also known in mammals as neurotensin receptor-3, is the archetypical member of a Vps10-domain (Vps10-D) that binds neurotrophic factors and neuropeptides. This domain constitutes the entire luminal part of Sortilin and is activated in the trans-Golgi network by enzymatic propeptide cleavage. The structure of the domain has been determined as a ten-bladed propeller, with up to 9 BNR or beta-hairpin turns in it. The mature receptor binds various ligands, including its own propeptide (Sort-pro), neurotensin, the pro-forms of nerve growth factor-beta (NGF)6 and brain-derived neurotrophic factor (BDNF)7, lipoprotein lipase (LpL), apo lipoprotein AV14 and the receptor-associated protein (RAP)1.
