re·nin

 (rē′nĭn, rĕn′ĭn)
n.
An enzyme released by the kidneys that cleaves a plasma protein to produce an inactive form of angiotensin which is then converted to an active form that raises blood pressure.

[Latin rēnēs, kidneys + -in.]

renin

(ˈriːnɪn)
n
(Biochemistry) a proteolytic enzyme secreted by the kidneys, which plays an important part in the maintenance of blood pressure
[C20: from reni- + -in]

re•nin

(ˈri nɪn)

n.
a proteolytic enzyme secreted by the kidneys that is involved in the release of angiotensin.
[< German Renin (1897) = Latin rēn(ēs) kidneys + German -in -in1]
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.renin - a proteolytic enzyme secreted by the kidneys; catalyzes the formation of angiotensin and thus affects blood pressure
peptidase, protease, proteinase, proteolytic enzyme - any enzyme that catalyzes the splitting of proteins into smaller peptide fractions and amino acids by a process known as proteolysis
Translations
