An expression system for the secretion of bioactive human granulocyte macrophage colony stimulating factor (GM-CSF) and other heterologous proteins from streptomyces

A gene expression system is used to produce heterologous biologically active proteins, in particular bioactive granulocyte macrophage colony stimulating factor ("GM-CSF"), secreted from a host selected from the Streptomyces genera. The gene expression system includes a regulatory nucleotid...

Beschreibung
Zusammenfassung:	A gene expression system is used to produce heterologous biologically active proteins, in particular bioactive granulocyte macrophage colony stimulating factor ("GM-CSF"), secreted from a host selected from the Streptomyces genera. The gene expression system includes a regulatory nucleotide sequence linked to a second nucleotide sequence encoding the heterologous protein. The regulatory sequence, encodes a peptide which directs the secretion of the heterologous protein in bioactive form from a host selected from the Streptomyces genera. The regulatory sequence includes a signal sequence and a promoter sequence. The second nucleotide sequence, which encodes GM-CSF or a biologically active derivative of GM-CSF, may be either natural or synthetic. In particular, the invention relates to an expression system for secreting bioactive, non-glycosylated, oxidized, therapeutically useful GM-CSF from a host selected from the Streptomyces genera.
