Phenyl ammonia lyase (PAL) involved in biosynthesis of phenolic compound in plants. Following are some statements regarding the action of PAL;

a) PAL catalyze conversion of phenyl alanine to p-coumaric acid

b) PAL catalyzes the conversion of phenyl alanine into trans-Cinnamic acid by elimination of an ammonia molecule

c) The activity of PAL is increased by environmental factors, such as low nutrient levels, light, and fungal infection

d) PAL is situated at a branch point between primary and secondary metabolism, so the reaction that it catalyzes is an important regulatory step in the formation of many phenolic compounds
