23 Genes involved in phenylpropanoid and lignin biosynthesis, such as phenylalanine ammonia lyase, cinnamoyl Co-A reductase, are also upregulated (I. Major and C. P. Constabel, unpublished), possibly contributing to leaf toughening via lignin-like depositions.91 Some of these genes may also ...
Define phenylalanine. phenylalanine synonyms, phenylalanine pronunciation, phenylalanine translation, English dictionary definition of phenylalanine. n. An essential amino acid, C9H11NO2, that occurs as a constituent of many proteins and is converted to
There were increases in the activity of phenylalanine ammonia-lyase and the level of chlorogenic acid, accompanied by the accumulation of a lignin-like polymer. All three changes were faster in Orion than in Majestic. Lignification was relatively slow and diffuse in the widespread infected area of...
Evidence of varied regioselectivity in amination reactions with AvPAL is surprising as this enzyme is an ammonia lyase and has never been shown to have discernible aminomutase activity [1]. Ammonia addition at both positions has only been observed in the enzyme family before with EncP fromStreptomy...

lyase (PAL)39, PPA-AT12, and PPY-AT16were correctly found to be localized in the cytosol, plastids, and cytosol, respectively (Supplementary Figures10and11). Moreover, CM activity in the presence of 20 µM and 500 µM chorismate was predominantly distributed in the cytosol and ...
Phytophthora root and stem rot of soybean [Glycine max (L.) Merr.] caused by Phytophthora sojae is a destructive disease worldwide. Phenylalanine ammonia-lyase (PAL) is one of the most extensively studied enzymes related to plant responses to biotic and

A gene cloning approach was based on the assumption that PAM would resemble the well known plant enzyme phenylalanine ammonia lyase. A phenylalanine ammonia lyase-like sequence acquired from a Taxus cuspidata cDNA library was expressed functionally in Escherichia coli and confirmed as the target amino...
Phenylalanine(tyrosine) ammonia-lyase (PAL) catalyzes the deamination of phenylalanine and tyrosine to cinnamic andp-coumaric acids, respectively. This is a crucial metabolic step connecting primarynitrogen metabolismthrough theshikimate pathway, with the allocation of carbon for the biosynthesis of phenylpr...
