Four proteinase inhibitors, A-II, A-III, B-I, and B-II, were isolated from seeds of Albizzia julibrissin (silk tree) of the subfamily Mimosoideae, which is often regarded as the most primitive group of the Leguminosae plants. They were all of the high-molecular weight type (21,600 for A-II and A-III, and 19,000 for B-I and B-II), and composed of two polypeptide chains, linked together by a disulfide bond. A-II (A-III) inhibited bovine trypsin and alpha-chymotrypsin probably at an identical site. B-I (BII) inactivated bovine alpha-chymotrypsin and porcine elastase. Sequence analyses of A-II and B-II revealed a considerable homology with soybean trypsin inhibitor (Kunitz) but suggested the presence of an about 20-amino acid insertion in the A-II molecule.
