==POLYGALACTURONASE FROM ERWINIA CAROTOVORA SSP. CAROTOVORA==
-
The crystal structure of the 40-kDa endo-polygalacturonase from Erwinia, carotovora ssp. carotovora was solved by multiple isomorphous replacement, and refined at 1.9 A to a conventional crystallographic R-factor of 0.198, and Rfree of 0.239. This is the first structure of a polygalacturonase and, comprises a 10 turn right-handed parallel beta-helix domain with two loop, regions forming a "tunnel like" substrate-binding cleft. Sequence, conservation indicates that the active site of polygalacturonase is, between these two loop regions, and comparison of the structure of, polygalacturonase with that of rhamnogalacturonase A from Aspergillus, aculeatus enables two conserved aspartates, presumed to be catalytic, residues, to be identified. An adjacent histidine, in accord with, biochemical results, is also seen. A similarity in overall electrostatic, properties of the substrate-binding clefts of polygalacturonase and, pectate lyase, which bind and cleave the same substrate, polygalacturonic, acid, is also revealed.
