Cloning, sequence and expression of two distinct human interleukin-1 complementary DNAs.

Two distinct but distantly related complementary DNAs encoding proteins sharing human interleukin-1 (IL-1) activity (termed IL-1 alpha and IL-1 beta), were isolated from a macrophage cDNA library. The primary translation products of the genes are 271 and 269 amino acids long, although expression in Escherichia coli of the carboxy-terminal 159 and 153 amino acids produces IL-1 biological activity.

Antimicrobial activity of synthetic bactenecin.

Bactenecin is an antimicrobial peptide isolated from bovine neutrophils. Bactenecin was synthesized by solid-phase peptide synthesis and renatured to a fully disulfide bonded form. The peptide inhibits the growth of Escherichia coli and Staphylococcus aureus at the same concentration reported for the peptide purified from bovine neutrophils. Bactenecin inhibits the growth of other medically important bacteria and yeast, and it kills the fungus Trichophyton rubrum. Acetylation and amidation of the amino- and carboxy-termini of bactenecin do not change its potency, while replacement of its two cysteine residues with serine decreases the potency.
