Subunits Comment Organism
More it is shown that lung stage L3 larvae mitochondria contain larval flavoprotein subunit (Fp) and adult flavoprotein subunit at a ratio of 1:0.56, and that most lung stage L3 larvae cytochrome b containing subunits CybS are of the adult form. This clearly indicates that the rearrangement of complex II begins with a change in the isoform of the anchor CybS subunit, followed by a similar change in the Fp subunit Ascaris suum

General Information

General Information Comment Organism
metabolism enzymatic activity, quinone content and complex II subunit composition in mitochondria of lung stage L3 (LL3) Ascaris suum larvae is examined. Lung stage L3 Ascaris suum larvae mitochondria show higher quinol–fumarate reductase activity than mitochondria of Ascaris suum at other stages. Ubiquinone content in lung stage L3 larvae mitochondria is more abundant than rhodoquinone. It is shown that lung stage L3 larvae mitochondria contain larval flavoprotein subunit (Fp) and adult flavoprotein subunit at a ratio of 1:0.56, and that most lung stage L3 larvae cytochrome b containing subunits CybS are of the adult form. This clearly indicates that the rearrangement of complex II begins with a change in the isoform of the anchor CybS subunit, followed by a similar change in the Fp subunit Ascaris suum
