| Type: | Conserved_site | Name: | Chorismate synthase, conserved site |
| Description: | Chorismate synthase () catalyzes the last of the seven steps in theshikimate pathway which is used in prokaryotes, fungi and plants for the biosynthesis of aromatic amino acids. It catalyzes the 1,4-trans eliminationof the phosphate group from 5-enolpyruvylshikimate-3-phosphate (EPSP) to form chorismate which can then be used in phenylalanine, tyrosine or tryptophanbiosynthesis. Chorismate synthase requires the presence of a reduced flavin mononucleotide (FMNH2 or FADH2) for its activity.Chorismate synthase from various sources shows a high degree of sequence conservation [, ]. It is a protein of about 360 to 400 amino-acid residues.This entry represents conserved regions from chorismate synthase that are rich in basic residues. | Short Name: | Chorismate_synthase_CS |
