Behaviour and properties of catechol-O-methyltransferase from human placenta.
A procedure is reported for the purification of human placental catechol-O-methyltransferase. The preparation is apparently homogeneous and behaves as a monomer with an approximate Mr of 23,000. The sequence of the first 21 amino acid residues from the N-terminal end of the protein is reported. The activity of the enzyme is strongly influenced by the nature of the buffer in which it is assayed.
