Norcoclaurine synthase (NCS) catalyzes a stereoselective Pictet–Spengler reaction to give the key intermediate, (S)-norcoclaurine in benzylisoquinolinealkaloidbiosynthesis. This family of alkaloids contains many bioactive molecules including morphine and berberine. Recently, NCS has been demonstrated to accept a variety of aldehydes and some ketones as substrates, leading to a range of chiral te
