Potato pectin falls to Phytophthora infestans is a plant oomycete pathogen that drove the potato famines of 1800s and continues afflict fields today. The polysaccharide makes up about third cell wall in potatoes. Sabbadin et al . identified family lytic monooxygenases (LMPOs) cleave are upregulated P. during infection. Silencing relevant LMPO gene successfully inhibited infections. These findin...

Lytic proteins encoded by bacterial genomes have been implicated in cell wall biosynthesis and recycling. The Bacillus cereus E33L ampD gene encodes a putative N-acetylmuramoyl-l-alanine amidase. This gene, expressed in vitro, produced a very stable, highly active lytic protein. Very low concentrations rapidly and efficiently lyse vegetative Bacillus anthracis cells.

Protamine and polyarginine had bacteriolytic effects indicating their primary sites of action as being wall components and showing bacterial diversity genetically determined. Shake-incubation was required in producing cell-lysis. Studies on Bacillus subtilis revealed a high polycation multiplicity per cell in lytic event displaying multihit lysing kinetics; bacteriolysis was inhibited by trypsi...

A 260-kDa structural cell wall protein was purified from sodium dodecyl sulfate-treated cell walls of Saccharomyces cerevisiae by incubation with Rarobacter faecitabidus protease I, which is a yeast-lytic enzyme. Amino acid sequence analysis revealed that this protein is the product of the SED1 gene. SED1 was formerly identified as a multicopy suppressor of erd2, which encodes a protein involve...

The negative impact of chemical pesticides on the environment and human health has contributed to introduction legal regulations that ensure reduction in use agrochemicals favor biological products. existing review literature, including our research, clearly shows ideal biocontrol agents are Trichoderma fungi. production antibiotics, lytic enzymes degrading cell walls plant pathogens, or induci...

A cell-wall-degrading activity was solubilized from young cells and from mother cell walls of CMo/W/a /w^ca by treatment with L i C l . The cytoplasmic enzyme hexokinase was not detectable in these extracts. The LiCl-solubilized activity increased in the cell cycle parallel to the release of autospores. The enzyme was purified on a chromatofocusing column followed by gel filtration. Sodium dode...
