Alpha-lactalbumin is the regulatory subunit of lactose synthase, changing the substrate specificity of galactosyltransferase from N-acetylglucosamine to glucose. C-type lysozymes are secreted bacteriolytic enzymes that cleave the peptidoglycan of bacterial cell walls. Structure is a multi-domain, mixed alpha and beta fold, containing four conserved disulfide bonds.
This domain forms an alpha-beta-two layer sandwich. It is found in the Bacillus subtilis proteins anti-sigma-V factor RsiV, which downregulates SigV activity [1], and peptidoglycan-N-acetylmuramic acid deacetylase PdaC, which catalyzes the deacetylat ...
This domain forms an alpha-beta-two layer sandwich. It is found in the Bacillus subtilis proteins anti-sigma-V factor RsiV, which downregulates SigV activity [1], and peptidoglycan-N-acetylmuramic acid deacetylase PdaC, which catalyzes the deacetylation of N-acetylmuramic acid which makes the peptidoglycan resistant to lysosyme [2]. It is found in association with Heat-shock cognate 70kd protein 44kd ATPase, Pfam:PF11738.
This entry represents a domain found in bacterial proteins, predominantly from Bacillota, Pseudomonadota and Bacteroidota. The domain is approximately 75-85 residues long and is usually located at the C-terminus. Structures of the MPT64 antigen from ...
This entry represents a domain found in bacterial proteins, predominantly from Bacillota, Pseudomonadota and Bacteroidota. The domain is approximately 75-85 residues long and is usually located at the C-terminus. Structures of the MPT64 antigen from Mycobacterium tuberculosis and the anti-sigma-V factor RsiV show that this region adopts a beta-grasp fold [1]. This domain occurs in several secreted or membrane-associated proteins, including the exported esterase Rv3036c (Swiss:I6YF08), which hydrolyses CC ester substrates with carbon chain lengths ranging from C2 to CC C14 [2], anti-sigma-V factor RsiV (Swiss:O05403), and peptidoglycan-N-acetylmuramic acid deacetylase PdaC (Swiss:O34798) [3]. In Clostridium difficile, RsiV is associated with the sigmaV lysozyme-resistance system [4]. This domain, often found adjacent to the PdaC domain (Pfam:PF13739), is predicted to form a homodimer.
