Chemical Nature of Agrocin 84 and Its Effect on a Virulent Strain of Agrobacterium tumefaciens

McCardell, Barbara A.
RESUMO
Agrocin 84, produced by Agrobacterium radiobacter K84, inhibited ribonucleic acid, deoxyribonucleic acid, and protein synthesis and amino acid transport in a susceptible, virulent strain of A. tumefaciens H-38-9. Cell motility was immediately stopped by action of the agrocin, 50% of the cells were killed within 15 min of contact, and the remainder were inhibited. Agrocin 84 is trypsin and pepsin resistant, but chemical analysis indicated a small peptide with a molecular weight of 2,500 containing six different amino acids, including nine molecules of glutamine or glutamic acid and seven molecules of serine.
