==Crystal structure of the polyamine oxidase Fms1 from yeast==
-
Fms1 is a rate-limiting enzyme for the biosynthesis of pantothenic acid in, yeast. Fms1 has polyamine oxidase (PAO) activity, which converts spermine, into spermidine and 3-aminopropanal. The 3-aminopropanal is further, oxidized to produce beta-alanine, which is necessary for the biosynthesis, of pantothenic acid. The crystal structures of Fms1 and its complex with, the substrate spermine have been determined using the single-wavelength, anomalous diffraction (SAD) phasing method. Fms1 consists of an, FAD-binding domain, with Rossmann fold topology, and a substrate-binding, domain. The active site is a tunnel located at the interface of the two, domains. The substrate spermine binds to the active site mainly via, hydrogen bonds and hydrophobic interactions. In the complex, C11 but not, C9 of spermine is close enough to the catalytic site (N5 of FAD) to be, oxidized. Therefore, the products are spermidine and 3-aminopropanal, rather than 3-(aminopropyl) 4-aminobutyraldehyde and 1,3-diaminoprone.
