title: The complete amino-acid sequence of histone H2B from the mollusc Patella granatina.
abstract: 1. From the marine mollusc, Patella granatina, a histone has been isolated. Its primary structure has been established and it has been designated histone H2Bpatella. It consists of a polypeptide chain of 121 amino acids. 2. In the carboxy-terminal two thirds of the molecule there is a highly degree of sequence homology to the corresponding region in calf histone H2B with identical residues in 95% of the positions. 3. In the N-terminal 22 amino acids histone H2Bpatella differs considerably from the mammalian histone H2B and it is shorter by four residues.
