cd06522	GH25_AtlA-like	7.40e-69	56	256	1	192	AtlA is an autolysin found in Gram-positive lactic acid bacteria that degrades bacterial cell walls by catalyzing the hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues. This family includes the AtlA and Aml autolysins from Streptococcus mutans which have a C-terminal glycosyl hydrolase family 25 (GH25) catalytic domain as well as six tandem N-terminal repeats of the GBS (group B Streptococcus) Bsp-like peptidoglycan-binding domain. Other members of this family have one or more C-terminal peptidoglycan-binding domain(s) (SH3 or LysM) in addition to the GH25 domain.
pfam01183	Glyco_hydro_25	4.78e-40	59	244	1	176	Glycosyl hydrolases family 25.
cd00599	GH25_muramidase	9.78e-31	57	241	1	170	Endo-N-acetylmuramidases (muramidases) are lysozymes (also referred to as peptidoglycan hydrolases) that degrade bacterial cell walls by catalyzing the hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues. This family of muramidases contains a glycosyl hydrolase family 25 (GH25) catalytic domain and is found in bacteria, fungi, slime molds, round worms, protozoans and bacteriophages. The bacteriophage members are referred to as endolysins which are involved in lysing the host cell at the end of the replication cycle to allow release of mature phage particles. Endolysins are typically modular enzymes consisting of a catalytically active domain that hydrolyzes the peptidoglycan cell wall and a cell wall-binding domain that anchors the protein to the cell wall. Endolysins generally have narrow substrate specificities with either intra-species or intra-genus bacteriolytic activity.
cd06415	GH25_Cpl1-like	2.40e-16	56	242	1	183	Cpl-1 lysin (also known as Cpl-9 lysozyme / muramidase) is a bacterial cell wall endolysin encoded by the pneumococcal bacteriophage Cp-1, which cleaves the glycosidic N-acetylmuramoyl-(beta1,4)-N-acetylglucosamine bonds of the pneumococcal glycan chain, thus acting as an enzymatic antimicrobial agent (an enzybiotic) against streptococcal infections. Cpl-1 belongs to the CP family of lysozymes (CPL lysozymes) which includes the Cpl-7 lysin. Cpl-1 has a glycosyl hydrolase family 25 (GH25) catalytic domain with an irregular (beta/alpha)5-beta3 barrel and a C-terminal cell wall-anchoring module formed by six similar choline-binding repeats (ChBr's). The ChBr's facilitate the anchoring of Cpl-1 to the choline-containing teichoic acid of the pneumococcal cell wall. Other members of this domain family have an N-terminal CHAP (cysteine, histidine-dependent amidohydrolases/peptidases) domain similar to that of the firmicute CHAP lysins and associated with endopeptidase activity. The Cpl-7 lysin is also included here as is LysB of Lactococcus phage, and the Mur lysin of Lactobacillus phage.
cd06414	GH25_LytC-like	8.41e-16	59	241	4	174	The LytC lysozyme of Streptococcus pneumoniae is a bacterial cell wall hydrolase that cleaves the beta1-4-glycosydic bond located between the N-acetylmuramoyl-N-glucosaminyl residues of the cell wall polysaccharide chains. LytC is composed of a C-terminal glycosyl hydrolase family 25 (GH25) domain and an N-terminal choline-binding module (CBM) consisting of eleven homologous repeats that specifically recognizes the choline residues of pneumococcal lipoteichoic and teichoic acids. This domain arrangement is the reverse of the major pneumococcal autolysin, LytA, and the CPL-1-like lytic enzymes of the pneumococcal bacteriophages, in which the CBM (consisting of six repeats) is at the C-terminus. This model represents the C-terminal catalytic domain of the LytC-like enzymes.
