title: Noncatalytic protein component of elastase from horse leucocytes. A protein with regulatory function.
abstract: 1. Noncatalytic protein component (NPC), a strongly acidic protein (pH = 4.5) was separated from native horse leucocyte elastase 1. 2. This protein reduces elastinolytic properties of elastases: 1 and 2A probably by decreasing their isoelectric points. 3. A possible regulatory role of this protein may be inferred from a higher affinity of elastase 1 to NPC rather than to elastin.
