Crystal structure of Tryptophan Synthase at 1.45 A resolution in complex with 2-aminophenol quinonoid in the beta site and the F9 inhibitor in the alpha site

Template:ABSTRACT PUBMED 23952479

Function

[TRPA_SALTY] The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. [TRPB_SALTY] The beta subunit is responsible for the synthesis of L-tryptophan from indole and L-serine.

About this Structure

4hpj is a 2 chain structure. Full crystallographic information is available from OCA.
