Pectinesterase catalyses the de-esterification of pectin into pectate and methanol.
2.
The organism was originally isolated because of its ability to digest pectin and pectate.
3.
*SP Lei et al ., Characterization of the Erwinia carotovora pelB gene and its product pectate lyase.
4.
The putative catalytic residues are in a similar location to those of the active site and substrate-binding cleft of pectate lyase.
5.
"' Pectate lyase "'( ) is an enzyme involved in the maceration and soft rotting of plant tissue.
6.
It has been suggested that the pollen expression of pectate lyase genes might relate to a requirement for pectin degradation during pollen tube growth.
7.
Kaolin-pectate, the original compound, was approved by the OTA ( Organic Trade Association ) for use in animals being produced for food.
8.
Polygalacturonase ( PG ) ( pectinase ) catalyzes the random hydrolysis of 1, 4-alpha-D-galactosiduronic linkages in pectate and other galacturonans.
9.
The first being a contribution to the stiffening of the cell wall by producing blocks of unesterified carboxyl groups that can interact with calcium ions forming a pectate gel.
10.
Both pectate lyase and P22 tailspike protein contain right-handed helices; left-handed versions have been observed in enzymes such as UDP-N-acetylglucosamine acyltransferase and archaeal carbonic anhydrase.
