Structural identity of immunoglobulin binding factor and prostatic secretory protein of human seminal plasma.
The amino acid sequence of the N-terminus of the immunoglobulin binding factor of human seminal plasma was determined. The initial 30 amino acids showed complete identity with that of prostatic secretory protein, beta-microseminoprotein and beta-inhibin. In conclusion, these proteins are probably a single entity.
