概要 In Pichia methanolica, expressions of methanol-metabolic enzymes were strictly regulated by the presence of oxygen, and induction of alcohol oxidase (AOD) isozymes was completely dependent on oxygen concentrations. ... These indicated that P. methanolica has the ability to recognize oxygen conditions and the respiratory chain should participate in the sensor for available oxygen. From these facts, there is organelle crosstalk between mitochondria and peroxisomes through nucleus gene regulation in order to control the consumption balance of available oxygen between the mitochondrial respiratory chain and peroxisomal AODs.
