[https://www.uniprot.org/uniprot/PGRP1_CAMDR PGRP1_CAMDR] Pattern receptor that binds to murein peptidoglycans (PGN) of Gram-positive bacteria. Has bactericidal activity towards Gram-positive bacteria. May kill Gram-positive bacteria by interfering with peptidoglycan biosynthesis. Binds also to Gram-negative bacteria. Involved in innate immunity. Is microbicidal for Gram-positive and Gram-negative bacteria and yeast. May function in intracellular killing of bacteria (By similarity).

== Publication Abstract from PubMed ==
 +
The peptidoglycan recognition protein PGRP-S is an innate immunity molecule that specifically interacts with microbial peptidoglycans and other pathogen-associated molecular patterns. We report here two structures of the unique tetrameric camel PGRP-S (CPGRP-S) complexed with (i) muramyl dipeptide (MDP) at 2.5 A resolution and (ii) GlcNAc and beta-maltose at 1.7A resolution. The binding studies carried out using surface plasmon resonance indicated that CPGRP-S binds to MDP with a dissociation constant of 10(-7) M, whereas the binding affinities for GlcNAc and beta-maltose separately are in the range of 10(-4) M to 10(-5) M, whereas the dissociation constant for the mixture of GlcNAc and maltose was estimated to be 10(-6) M. The data from bacterial suspension culture experiments showed a significant inhibition of the growth of Staphylococcus aureus cells when CPGRP-S was added to culture medium. The ELISA experiment showed that the amount of MDP-induced production of TNF-alpha and IL-6 decreased considerably after the introduction of CPGRP-S. The crystal structure determinations of (i) a binary complex with MDP and (ii) a ternary complex with GlcNAc and beta-maltose revealed that MDP, GlcNAc, and beta-maltose bound to CPGRP-S in the ligand binding cleft, which is situated at the interface of molecules C and D of the homotetramer formed by four protein molecules A, B, C, and D. In the binary complex, the muramyl moiety of MDP is observed at the C-D interface, whereas the peptide chain protrudes into the center of tetramer. In the ternary complex, GlcNAc and beta-maltose occupy distinct non-overlapping positions belonging to different subsites.
