The complete amino acid sequence of the variable region of Bence-Jones protein Mev. from a patient suffering from multiple myeloma and generalized amyloidosis is presented. The amino acid sequence of the Bence-Jones protein Mev. is related to other human kappa-immunoglobulin L-chains of subgroup I. With valine established in Position 191 of the constant region, it is of the Inv (3) allotype. Two types of the Bence-Jones protein Mev. were found, one beginning with the typical N-terminal aspartic acid, and another lacking the N-terminal tripeptide and commencing with methionine in Position 4. A unique insertion of glutamic acid after Position 95 was found in the Bence-Jones protein. This is the position where the V- and J-gene segments join. The J-region of Bence-Jones protein Mev. exhibits some marked differences to the five J-regions recently established by nucleic acid sequencing. This suggests, that there must be considerable polymorphism in human kappa-J-genes. The amyloid fibril protein from the same patient (A Mev.) has also been sequenced up to Position 27. It was found to be identical to the sequence of Bence-Jones protein Mev. commencing with aspartic acid. The molecular mass of the amyloid fibril protein was found to be between 11 000 and 12 000 Da as estimated by gelfiltration and dodecyl sulfate-polyacrylamide electrophoresis.
