Cyctochrome oxidase

WebPurification of cytochrome c oxidase was carried out from the purified mitochondria by using combination techniques of detergent solubilization and reduced cytochrome c-agarose affinity chromatography. The 560-fold purified enzyme with 3.6% yield was obtained and it had low catalytic efficiency with a kcat/Km of 5.9 x 10(-5) M-1 x min-1. The ... WebAll patients had increased serum lactate and decreased levels and activity of mitochondrial respiratory complex IV (summary by Massa et al., 2008 and Abdulhag et al., 2015). For a discussion of genetic heterogeneity of mitochondrial complex IV (cytochrome c oxidase) deficiency, see 220110.
