Conserved Site

Chorismate synthase, conserved site (IPR020541)

Short name: Chorismate_synthase_CS


Chorismate synthase (EC: catalyzes the last of the seven steps in the shikimate pathway which is used in prokaryotes, fungi and plants for the biosynthesis of aromatic amino acids. It catalyzes the 1,4-trans elimination of the phosphate group from 5-enolpyruvylshikimate-3-phosphate (EPSP) to form chorismate which can then be used in phenylalanine, tyrosine or tryptophan biosynthesis. 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 [PMID: 1718979, PMID: 1837329]. 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.
