説明

A saccharifying pectate trans-eliminase was found in the cells of Erwinia aroideae. This enzyme differs from known pectate trans-eliminate 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.
