| Abstract: | A saccharifying pectate trans-eliminase was found in the cells of Erwinia aroideae. This enzyme differs from known pectate trans-eliminase in the next two points. It degrades pectic acid liberating 4,5-unsaturated digalacturonic acid from the chain end of the molecule. It does not require calcium ion.Some properties of 4,5-unsaturated digalacturonic acid, the main product of the saccharifying pectate trans-elimination, were also described in this paper. |
