Noncatalytic protein component of elastase from horse leucocytes. A protein with regulatory function

Int J Biochem. 1988;20(1):105-8. doi: 10.1016/0020-711x(88)90019-5.

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.
