Preliminary Crystallographic Data and Primary Sequence for Anti-peptide Fab' B13I2 and Its Complex with the C-helix Peptide from Myohemerythrin

Year: 1989

Type: article

Abstract: Crystals of the Fab' fragment from the monoclonal anti-peptide antibody B1312 and of the Fab'-peptide antigen complex have been characterized. The monoclonal antibodies were raised against a synthetic homologue of the C-helix of myohemerythrin (residues 69-87 in myohemerythrin). The Fab'-peptide complex crystallizes in space group P6322 with unit cell dimensions a = b = 142.5 A, c = 101.5 A, alpha = beta = 90 degrees, gamma = 120 degrees, and Z = 1. The native Fab' crystallizes in space group P212121 with unit cell dimensions a = 98.0 A, b = 151.7 A, c = 80.8 A, alpha = beta = gamma = 90 degrees, and Z = 2. Both crystal forms diffract to beyond 2.6 A resolution. We also report the cDNA and predicted amino acid sequences for the variable regions of both the light and heavy chains of this anti-peptide antibody.
