Angiotensin converting enzyme (ACE) was already discovered in insects in 1994, but its physiological role is still enigmatic. We have addressed this problem by purifying four new ACE substrates from the ovaries of the grey fleshfly, Neobellieria bullata. Their primary structures were identified as NKLKPSQWISLSD (Neb-ODAIF-11)13), NKLKPSQWI (Neb-ODAIF-11)9), SLKPSNWLTPSE (Neb-ODAIF-2) and LEQIYHL. Database analysis showed significant homology with amino acid sequence stretches as present in the N-terminal part of several fly yolk proteins....

Angiotensin-converting enzyme-2 (ACE2) may play an important role in cardiorenal disease and it has also been implicated as a cellular receptor for the severe acute respiratory syndrome (SARS) virus. The ACE2 active-site model and its crystal structure, which was solved recently, highlighted key differences between ACE2 and its counterpart angiotensin-converting enzyme (ACE), which are responsible for their differing substrate and inhibitor sensitivities.

A protocol to follow the processing of angiotensin I into angiotensin II by rabbit angiotensin-converting enzyme (ACE) and its inhibition by a novel natural antagonist, the leech osmoregulator factor (LORF) using capillary zonal electrophoresis is described. The experiment was carried out using the Beckman PACE system and steps were taken to determine (a) the migration profiles of angiotensin and its yielded peptides, (b) the minimal amount of angiotensin II detected, (c) the use of different electrolytes and (d) the concentration of inhibitor. ...

Numerous transmembrane proteins, including the blood pressure regulating angiotensin converting enzyme (ACE) and the Alzheimer’s disease amyloid precursor protein (APP), are proteolytically shed from the plasma membrane by metalloproteases. We have used an antisense oligo-nucleotide (ASO) approach to delineate the role of ADAM10 and tumour necrosis factor-aconverting enzyme (TACE;ADAM17) in theectodomainsheddingofACEand APP from human SH-SY5Y cells.

The crystal structure of a Drosophila angiotensin-converting enzyme (ANCE) has recently been solved, revealing features important for the binding of ACE inhibitors and allowing molecular comparisons with the structure of human testicular angiotensin-converting enzyme (tACE). ACER is a secondDrosophilaACE that displays both common and dis-tinctive properties.

Somatic angiotensin-converting enzyme (ACE) contains two homologous domains, each bearing a functional active site. Studies on the selectivity of these ACE domains towards either substrates or inhibitors have mostly relied on the use of mutants or isolated domains of ACE.

In the present study, an isoform of angiotensin-converting enzyme was characterized from the testis of a decapod crustacean, the crayfish Asta-cus leptodactylus. Angiotensin-converting enzyme cDNA, obtained by 3¢-to5¢ RACE of testis RNAs, codes for a predicted one-domain protein similar to the mammalian germinal isoform of angiotensin-converting enzyme.
