More | SDH enzymes exist in opened and closed conformational states. In the ternary structure of Aquifex aeolicus SDH (PDB ID 2HK9), three loops in the shikimate binding domain are shifted about 5 A toward the NADP++ binding site compared to their position in an unliganded structure of the same enzyme (PDB ID 2HK8). The closed form of the structure thus brings the bound shikimate and NADP+ molecules into close proximity, facilitating a hydride transfer between the shikimate C5-hydroxyl and C4 of the NADP+ nicotinamide ring | Aquifex aeolicus |
More | the SDH domain is connected via its N-terminus to the DHQ module | Arabidopsis thaliana |

SDH is part of the Arom complex, that catalyzes both the third and fourth reactions in the shikimate pathway. This large enzyme complex contains five functional domains that are equivalent to the monofunctional enzymes (in bacteria) catalyzing reactions two through six of the shikimate pathway | Aspergillus nidulans |
additional information | in plants such as Arabidopsis thaliana and Populus trichocarpa, shikimate dehydrogenase SDH is fused to an anabolic (type I) dehydroquinate dehydratase (DHQ), forming a bifunctional protein known as the DHQ-SDH complex, cf. EC 4.2.1.10 and EC 1.1.1.25. The close proximity of domains in the DHQ-SDH complex may facilitate substrate channeling between enzyme active sites, minimizing the loss of shikimate pathway intermediates to competing processe. Crystallization of the Arabidopsis thaliana protein with shikimate bound in the SDH domain and tartrate (a component of the crystallization solution) in the DHQ domain reveals a V-shaped orientation of the domains. Addition of NADP+ to DHQSDH crystals already containing shikimate in the SDH domain results in the production of 3-dehydroshikimate by the SDH domain and the transfer of the compound to the DHQ active sites | Arabidopsis thaliana |
