Cystathionine

  

Cystathionine

  [sis-tuh-thahy-uh-neen, -nin]
Cystathionine is an intermediate in the synthesis of cysteine.

It is generated from homocysteine and serine by cystathionine beta synthase.

It is cleaved into cysteine and α-ketobutyrate by cystathionine gamma-lyase.

An excess in the urine is called cystathioninuria.
