DBH can be a tetrameric glycoprotein that contains subunits of seventy seven and 73 kDa, as determined by sodium dodecyl sulfate (SDS) gel electrophoresis. A full-duration clone encodes a polypeptide chain of 578 amino acids [7]. The enzyme is concentrated inside the vesicles that retail outlet catecholamines; the vast majority of DBH is certain to the inner vesicular membrane, but some is no cost throughout the vesicles. DBH is launched along with catecholamines from nerves and through the adrenal gland which is present in plasma.
