Sulfide Quinone Reductase-like, or Sulfide quinone reductase-like (yeast), is a human gene encoded by SQRDL. It may also be known as: Sulfide:quinone oxidoreductase, mitochondrial; SQOR; CGI-44; PRO1975. The encoded protein is an enzyme with an amino acid length of 450 and a mass of 50.0 kDa. Other isoforms may exist. Sulfide Quinone Reductase-like is a member of the SQRD family. Homologs of this gene exist in other organisms, including: Frog.
