Abstract: Morinda citrifolia is a fruit-bearing tree in the coffee family of Rubiaceae. Morinda is considered to have biological properties in traditional medicine. Morinda citrifolia is contain many protein structure but specially take a limited protein and study a insilico analysis.Morinda citrifolia is contain many enzymes but especially in phenylalanine ammonialyase. Phenylalanine ammonia lyase is cure for the inborn error of protein metabolism(phenylketoneuria). Phenylalanine ammonia lyase is found widely in plants, as well as some bacteria, yeast, and fungi, with isoenzymes existing within many different species. This study is usually facilitated by accurate three-dimensional (3-D) structure of the protein. Number of known protein sequences and structures as well as improvements in the modeling software.

Keywords: Morinda citrifolia , Bioinformatics , traditional medicine, Phenylalanine ammonia lyase.
