4.2.2.2	additional information	constitutive enzyme	
4.2.2.2	additional information	the enzyme is involved in pathogenesis	
4.2.2.2	additional information	pectin or pectic acid as inducer	
4.2.2.2	additional information	enzyme production is repressed by glucose	
4.2.2.2	additional information	the pectate lyase isoenzyme PelS appears to alter the final symptoms in infected cucumber cotyledons without contributing to pathogenicity or altering host range	
4.2.2.2	additional information	as the external pH increases from 4.0 to 6.0, pectate lyase and other extracellular proteins are secreted and accumulate. Nitrogen assimilation also is required for enzyme secretion at pH 6.0. The ambient pH and the nitrogen source are independent regulatory factors for processes linked to secretion of pectate lyase and virulence of Colletotrichum gloeosporioides	
4.2.2.2	additional information	colonization of plant tissues by the phytopathogen Erwinia chrysanthemi E16 is aided by the activities of the pectate lyase isoenzymes, which depolymerize the polygalacturonic acid component of the plant cell walls	
4.2.2.2	additional information	pectate lyase A is a virulence factor for soft rot diseases in plants	
4.2.2.2	additional information	pectate lyase A is a virulence factor secreted by the plant pathogenic bacterium Erwinia chrysanthemi	
4.2.2.2	additional information	the enzyme is involved in degradation of the pectate portion of the primary plant cell wall	
4.2.2.2	additional information	the enzyme secreted by the bacterium into the human large intestine cooperatively digests pectic substances, producing mainly 4,5-unsaturated digalacturonic acid with the participation of the pectin methyltransferase	
4.2.2.2	additional information	the pathogenicity of Colletotrichum gloeosporioides is dependent on its ability to secrete pectate lyase. The host pH in pericarp regulates the secretion. Secretion is detected when the pH reaches 5.8 and the level of secretion increases up to pH 6.5	
4.2.2.2	additional information	the enzyme plays an important role in plant-nematode interactions	
4.2.2.2	additional information	in the completed genome of Arabidopsis, there are 26 genes that encode pectate lyase-like proteins. The stability of transcripts of PLLs varies considerably among different genes. Complex regulation of expression of PLLs and involvement of PLLs in some of the hormonal and stress responses. several PLLs are expressed highly in pollen, suggesting a role for these in pollen development and/or function	
4.2.2.2	additional information	optimization of chemical and physical parameters affecting the activity of pectate lyase	
4.2.2.2	additional information	the Gr-PEL2 protein is capable of inducing profound changes in the plant morphology, not related to tissue maceration or soft rot	
4.2.2.2	additional information	when the fungus is grown at pH 4.0 or 6.0 in the absence of a nitrogen source, neither pelB (encoding pectate lyase) transcription nor pectate lyase secretion is detected. pelB transcription and pectate lyase secretion are both detected when Colletotrichum gloeosporioides is grown at pH 6.0 in the presence of ammonia accumulated from different nitrogen sources. The early accumulation of ammonia induces early pelB expression and pectate lyase secretion. Nit mutants of Colletotrichum gloeosporioides, which cannot utilize KNO3 as a nitrogen source, do not secrete ammonia, alkalinize the medium, or secrete pectate lyase. If Nit mutants are grown at pH 6.0 in the presence of glutamate, then pectate lyase secretion is induced
