'''ARCHITECTURE OF THE THERMOMYCES LANUGINOSUS FUNGAL FATTY ACID SYNTHASE AT 5 ANGSTROM RESOLUTION.'''<br />


==Overview==
==ARCHITECTURE OF THE THERMOMYCES LANUGINOSUS FUNGAL FATTY ACID SYNTHASE AT 5 ANGSTROM RESOLUTION.==
All steps of fatty acid synthesis in fungi are catalyzed by the fatty acid, synthase, which forms a 2.6-megadalton alpha6beta6 complex. We have, determined the molecular architecture of this multienzyme by fitting the, structures of homologous enzymes that catalyze the individual steps of the, reaction pathway into a 5 angstrom x-ray crystallographic electron density, map. The huge assembly contains two separated reaction chambers, each, equipped with three sets of active sites separated by distances up to, approximately 130 angstroms, across which acyl carrier protein shuttles, substrates during the reaction cycle. Regions of the electron density, arising from well-defined structural features outside the catalytic, domains separate the two reaction chambers and serve as a matrix in which, domains carrying the various active sites are embedded. The structure, rationalizes the compartmentalization of fatty acid synthesis, and the, spatial arrangement of the active sites has specific implications for our, understanding of the reaction cycle mechanism and of the architecture of, multienzymes in general.
