Binary structure of the two-domain (3R)-hydroxyacyl-CoA dehydrogenase from rat peroxisomal multifunctional enzyme type 2 at 2.38 A resolution.
A.M.Haapalainen, M.K.Koski, Y.M.Qin, J.K.Hiltunen, T.Glumoff.
The crystal structure of (3R)-hydroxyacyl-CoA dehydrogenase of rat peroxisomal multifunctional enzyme type 2 (MFE-2) was solved at 2.38 A resolution. The catalytic entity reveals an alpha/beta short chain alcohol dehydrogenase/reductase (SDR) fold and the conformation of the bound nicotinamide adenine dinucleotide (NAD(+)) found in other SDR enzymes. Of great interest is the separate COOH-terminal domain, which is not seen in other SDR structures. This domain completes the active site cavity of the neighboring monomer and extends dimeric interactions. Peroxisomal diseases that arise because of point mutations in the dehydrogenase-coding region of the MFE-2 gene can be mapped to changes in amino acids involved in NAD(+) binding and protein dimerization.

Figure 4.
Figure 4. Electron Density around NAD^+The figure shows an F[o] - F[c] map, contoured at 2.5 s, just before including the NAD^+. Ser151, Tyr164, and Lys168 form the catalytic triad needed in the hydride transfer reaction. In the structure of dhDSCP-2LD, the close contact of Asp40 with the hydroxyl groups of the adenine ribose does not leave enough space for the phosphate group in NADP(H). This guides specificity toward NAD(H). The figure was prepared with Swiss-PdbViewer [67].

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
