Method: X-ray diffraction, Resolution 2Å Ligands: BUL Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function LYSC2_ONCMY Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents. Has antibacterial activity against the Gram positive bacterium P.citreus. Has no antibacterial activity against the Gram negative bacteria E.coli and Y.ruckeri. Does not have hemolytic activity against trout erythrocytes. Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMed Bulgecin, a sulfonated glycopeptide produced by Pseudomonas acidophila and Pseudomonas mesoacidophila, induces bulge formation and enhances lysis of bacterial cell walls when used in combination with beta-lactam antibiotics. The compound does not itself exhibit any antibacterial activity, but has been shown to inhibit a soluble lytic transglycosylase (SLT70) from Escherichia coli which has a lysozyme-like domain. Recently, the crystal structure of an SLT-bulgecin complex has been determined to 3.5 A resolution. We report here the crystal structure of a complex between lysozyme from the rainbow trout (RBTL) and bulgecin A at 2.0 A resolution. As for the SLT-bulgecin complex, bulgecin is bound with the glycosaminyl moiety in subsite C and the proline residue in site D of the active-site cleft of RBTL, where it makes hydrogen-bonding interactions with the catalytic residues. The taurine moiety is bound to the left side of subsites E and F in the lower part of the active-site cleft. From the observed position of the bulgecin molecule, it seems reasonable that it is an inhibitor of rainbow trout lysozyme. The lysozymes may, in general, be a target for the design of a novel type of antibiotics distinct from the beta-lactams which are insensitive to the muramidases.
