Certain bacteria from the genus Streptomyces are currently used as biological control agents against plant pathogenic fungi. Hydrolytic enzymes that degrade fungal cell wall components, such as chitinases, are suggested as one possible mechanism in biocontrol interactions. Adaptive evolution of

LysM motifs are carbohydrate-binding modules found in prokaryotes and eukaryotes. They have general N-acetylglucosamine binding properties and therefore bind to chitin and related carbohydrates. In plants, plasma-membrane-bound proteins containing LysM motifs are involved in plant defence responses, but also in

The binding of Autographa californica multiple nucleopolyhedrovirus chitinase (CHIA) to viral cathepsin protease progenitor (proV-CATH) governs cellular/endoplasmic reticulum (ER) coretention of CHIA and proV-CATH, thus coordinating simultaneous cellular release of both host tissue-degrading enzymes upon host cell death. CHIA is

Three acidic residues in the DXDXE sequence motif are suggested to play a concerted role in the catalysis of Vibrio harveyi ChiA. An increase in the optimum pH of 0.8 units in mutant D313A/N indicates that Asp313 influences the pKa
