Ca(2+)-Transporting ATPase, Enzyme Commission 7.2.2.10

  The H(+)-Transporting ATP Synthase , Enzyme Commission 7.1.2.2 was the topic of an earlier blog post.  Here I present the Ca(2+)-Transporting ATPase, Enzyme Commission 7.2.2.10,  As shown in the above diagram, it is part of the “sarcoplasmic reticulum”, and a membrane protein of the plasma membrane as well.  On the  Roche Biochemical webpage it … Continue reading Ca(2+)-Transporting ATPase, Enzyme Commission 7.2.2.10

H(+)-Transporting ATP Synthase, Enzyme Commission 7.1.2.2

The Na-K ATPase [Enzyme Commission 7.2.2.13] was the topic of earlier blog post. Here I present the H(+)-Transporting ATP Synthase, Enzyme Commission 7.1.2.2.  As shown in the diagram above, it is part of “respiratory chain” and “oxidative phosphorylation”.  In the Roche Biochemical webpage  it is located at “P” (shown in the diagram above) , and … Continue reading H(+)-Transporting ATP Synthase, Enzyme Commission 7.1.2.2

Na(+)/K(+)-exchanging ATPase, Enzyme Commission 7.2.2.13 , Jen Skou discovered in 1957.

  Jen Christian Skou discovery of the “Sodium Pump” in 1957 was a pioneering step in cellular energetics.  In a human body this single enzyme accounts for two-third of body energy.  Ubiquitous in cells of the animal kingdom, 40 years after the discovery Skou received the 1997 Nobel Prize.  Note the magnesium is a cofactor … Continue reading Na(+)/K(+)-exchanging ATPase, Enzyme Commission 7.2.2.13 , Jen Skou discovered in 1957.
