Pectic Enzymes
Indoleacetic acid (IAA) and/or inhibitors of DNA, RNA or protein synthesis were added to the apex of decapitated seedlings of Pisum sativum L. var. Alaska. At various times up to 4 days, enzymic protein was extraoted from a segment of epicotyl immediately below the apex and assayed for its ability to hydrolyse polysaccharides or their derivatives. With the exception of am;ylase, the total amoun...
متن کاملRelationship of Pectic Enzymes to Abscission
A comprehensive review of work pertinent to changes in the separation zone prior to abscission is presented. Since these changes are largely pectic in nature the involvement of pectic enzymes is suggested. The results obtained for the role of pectin methylesterase ( PME) in abscission arc as follows: ( 1 ) A localization of PME activity in the abscission zone of tobacco pedicels was established...
متن کاملProduction of pectic enzymes in yeasts.
When grown in the appropriate medium, several yeast species produce pectinases able to degrade pectic substances. It is mainly exocellular endopolygalacturonases that break pectins or pectate down by hydrolysis of alpha-1,4-glycosidic linkages in a random way. Biochemical characterisation of these enzymes has shown that they have an optimal pH in the acidic region and an optimal temperature bet...
متن کاملNotes on Some Remedies. XXIII. Blood Transfusion, Part II
As the essential cause of shock in acute haemorrhage is the resulting low blood volume, the restoration of blood volume by transfusion is the most important step in treatment. Intravenous saline or glucose-saline infusions are inadequate as their effect is only transitory, although they are a valuable supplementary when dehydration complicates the picture. Definite indications for transfusion a...
