Crystal Structure of Alcohol Oxidase from Pichia pastoris
FAD-dependent alcohol oxidases (AOX) are key enzymes of methylotrophic organisms that can utilize lower primary alcohols as sole source of carbon and energy. Here we report the crystal structure analysis of the methanol oxidase AOX1 from Pichia pastoris. The crystallographic phase problem was solved by means of Molecular Replacement in combination with initial structure rebuilding using Rosetta...
متن کاملStructure of Alcohol Oxidase from Pichia pastoris by Cryo-Electron Microscopy
The first step in methanol metabolism in methylotrophic yeasts, the oxidation of methanol and higher alcohols with molecular oxygen to formaldehyde and hydrogen peroxide, is catalysed by alcohol oxidase (AOX), a 600-kDa homo-octamer containing eight FAD cofactors. When these yeasts are grown with methanol as the carbon source, AOX forms large crystalline arrays in peroxisomes. We determined the...

متن کاملNon-repressing carbon sources for alcohol oxidase (AOX1) promoter of Pichia pastoris.
The growth of Pichia pastoris in a mixture of either glycerol or glucose and methanol follows a diauxic growth, with C1 utilizing enzymes being repressed. Therefore, these carbon sources can not be used as a mixture with methanol to simultaneously grow P. pastoris and induce C1 utilizing enzymes, especially in a shake flask cultures of AOX-deficient P. pastoris. Among the alternative carbon sou...
