Pancreatic elastase is a form of elastase that is produced in the acinar cells of the pancreas, initially produced as an inactive zymogen and later activated in the duodenum by trypsin. Elastases form a subfamily of serine proteases, characterized by a distinctive structure consisting of two beta barrel domains converging at the active site that hydrolyze amides and esters amongst many proteins in addition to elastin, a type of connective tissue that holds organs together. Pancreatic elastase 1 is a serine endopeptidase, a specific type of protease that has the amino acid serine at its active site. Although the recommended name is pancreatic elastase, it can also be referred to as elastase-1, pancreatopeptidase, PE, or serine elastase.

  • Die Pankreas-Elastase (Elastase-1, chymotrypsin-like elastase 1 Gen-Name: CELA1) ist ein Verdauungsenzym, das in der Bauchspeicheldrüse aller Wirbeltiere gebildet wird. Das Enzym spaltet Proteine auf (so genannte Endopeptidase) und gehört allgemein zu den Elastasen. Es wird mit anderen Verdauungsenzymen, wie beispielsweise der Alpha-Amylase, der Lipase, Trypsin und Phospholipasen von der Bauchspeicheldrüse in den Dünndarm abgegeben. (de)

Elastases form a subfamily of serine proteases, characterized by a distinctive structure consisting of two beta barrel domains converging at the active site that hydrolyze amides and esters amongst many proteins in addition to elastin, a type of connective tissue that holds organs together. Pancreatic elastase 1 is a serine endopeptidase, a specific type of protease that has the amino acid serine at its active site. Although the recommended name is pancreatic elastase, it can also be referred to as elastase-1, pancreatopeptidase, PE, or serine elastase. The first isozyme, pancreatic elastase 1, was initially thought to be expressed in the pancreas. However it was later discovered that it was the only chymotrypsin-like elastase that was not expressed in the pancreas. In fact, pancreatic elastase is expressed in basal layers of epidermis (at protein level). Hence pancreatic elastase 1 has been renamed elastase 1 (ELA1) or chymotrypsin-like elastase family, member 1 (CELA1). For a period of time, it was thought that ELA1 / CELA1 was not transcribed into a protein. However it was later discovered that it was expressed in skin keratinocytes. Clinical literature that describes human elastase 1 activity in the pancreas or fecal material is actually referring to chymotrypsin-like elastase family, member 3B (CELA3B). (en)
  • L'elastasi pancreatica è una forma di elastasi prodotta dalle cellule acinose del pancreas come zimogeno inattivo il quale è attivato nel lume del duodeno dalla azione clivante della tripsina. Come le altre elastasi, fa parte di una sottofamiglia di serinoproteasi caratterizzate da una struttura peculiare contenente due domini a barile β che convergono nel sito attivo, il quale idrolizza amidi, legami estere ed elastina. Sebbene il nome maggiormente utilizzato sia quello di elastasi pancreatica, spesso ci si riferisce a tale enzima anche con i nomi elastasi 1, pancreatopeptidasi, PE o serinoelastasti. Il primo isoenzima scoperto, inizialmente denominato elastasi pancreatica 1, era erroneamente ritenuto prodotto dal pancreas. Analisi successive dimostrarono che tale enzima era invece una proteina chimotripsino-simile e per un certo periodo fu ritenuto che il suo gene non fosse mai trascritto nell'uomo. Dopo ulteriori studi fu scoperto che la proteina era in realtà espressa a bassi livelli dai cheratinociti dello strato basale dell'epidermide. Per tale motivo l'elastasi pancreatica 1 scoperta in origine fu ridenominata "elastasi 1" (ELA1) o chymotrypsin-like elastase family, member 1 (CELA1). La letteratura clinica che tratta della "elastasi 1" prodotta nel pancreas e presente nel materiale fecale si riferisce invece alla elastasi chimotripsino-simile 3B (CELA3B). Grazie alle sue caratteristiche biochimiche, l'elastasi pancreatica non è degradata durante l'intero transito intestinale per cui l'analisi della sua presenza a livello del materiale fecale risulta efficace nel riflettere lo stato funzionale del pancreas esocrino.

  • Pancreaselastase is een eiwitsplitsend enzym, dat door middel van hydrolysering bijdraagt aan de afbraak en vertering van eiwitten. Het wordt in de alvleesklier aangemaakt als pro-elastase (een Pro-enzym) en vervolgens in de twaalfvingerige darm met behulp van het enzym trypsine omgezet tot elastase. (nl)
  • Панкреатическая эластаза - фермент, вырабатываемый ацинарными клетками поджелудочной железы. Синтезируются в виде неактивных предшественников, называемых проэластазами, которые накапливаются в ацинарных клетках поджелудочной железы. Высвобождается из поджелудочной железы в тонкий кишечник вместе с другими пищеварительными ферментами, такими как альфа-амилаза, липаза, трипсин и фосфолипазы. Активируется в двенадцатиперстной кишке трипсином. Cпособствует деградации и перевариванию эластина и других белков путем гидролиза. В отличие от других протеин-расщепляющих ферментов трипсина и химотрипсина, эластаза остается активной даже после прохождения кишечника. В результате изучение содержания эластазы в фекалиях может показать, функционирует ли поджелудочная железа правильно. Пониженный уровень может быть следствием вторичного сахарного диабета, желчнокаменной болезни, остеопороза, панкреатита, муковисцидоза, нарушений работы поджелудочной железы и кишечника. (ru)
