Human Lung Angiotensin Converting Enzyme

Angiotensin Converting Enzyme in Sarcoidosis

Human lung angiotensin converting enzyme. Purification and antibody preparation.

To enable its immunohistologic localization, angiotensin converting enzyme (EC 3.4.15.1) from human lung was solubilized by trypsinization and purified approximately 2,660-fold to apparent homogeneity from a washed lung particulate fraction. The specific activity of pure enzyme was estimated to be 117 mumol/min per mg protein with the substrate hippuryl-l-histidyl-l-leucine. Consistent with pre...

Angiotensin-converting enzyme and human physical performance

Genes undoubtedly play a role in the development of a successful athlete. This view has flourished on anecdotes such as the observation of a child who displays the same aptitude for a particular sport as one of their parents, or a pair of sisters who both excel in the same discipline. However, the conclusions made from this type of observation have an obvious limitation: that similar environmen...

Angiotensin-converting Enzyme from Human Tissues

Angiotensin-converting enzyme was purified from human lung, kidney, testis, blood plasma, and seminal plasma using a facile two-step protocol which included affinity chromatography on Sepharose-bound lisinopril followed by either gel filtration or hydroxylapatite chromatography. Molecular mass for converting enzyme from all sources except testis was 140 kDa. That from testis consisted of both a...
