Exact function not known, but clearly affects cell wall composition.CATALYTIC ACTIVITY:Eliminative cleavage of (1->4)-alpha-D- galacturonan to give oligosaccharides with 4-deoxy-alpha-D-galact- 4-enuronosyl groups at their non-reducing ends.COFACTOR:Binds 1 calcium ion. Required for its activity (By similarity).TISSUE SPECIFICITY:Expressed equally in mature leaves, buds, flowers, rosettes and roots.DOMAIN:The C-terminal domain not found in other pectate lyase- like protein is required for PMR6 function since the pmr6-2 mutation confers resistance by introducing a frameshift in the mature mRNA which eliminates the C-terminal domain.MISCELLANEOUS:Pmr6 mutations are pleiotropic, indicating that PMR6 plays a unique role in normal plant growth and development.The increased resistance in mutants is not mediated by the constitutive activation of the SA-dependent or the JA/ethylene- dependent defense pathway.MISCELLANEOUS:Cell walls of mutant plants are enriched for pectins with a lower degree of esterification and an alteration in the H bonding environment of cellulose microfibrils.SIMILARITY:Belongs to the polysaccharide lyase 1 family.SEQUENCE CAUTION:Sequence=CAB41092.1; Type=Erroneous gene model prediction; "
