摘要: Publisher Summary This chapter discusses the isoenzymes and compartmentation in regulation of phenolic metabolism. Primary metabolism is linked by well-known enzyme phenylalanine ammonia-lyase (PAL), which converts l -phenylalanine into cinnamic acid. has been shown to be present different cellular fractions with other enzymes involved Such organelles are synthesis coumarins. In some plants, chloroplasts can also shorten lateral three carbon chain acids benzoic acids. nonphotosynthetic organs, PAL associated mitochondria or microbody-type C6-C1 units from C6-C3 compounds. The microsomal fraction, may contain activity tightly membrane bound cinnamate k-hydroxylase, gives rise general phenylpropanoid pathway. data suggest a subcellular location depending on specific expression
