Identification
NameCysteine desulfurase, mitochondrial
Synonyms
  • tRNA-splicing protein SPL1
Gene NameNFS1
Enzyme Class
Biological Properties
General FunctionInvolved in metabolic process
Specific FunctionCatalyzes the removal of elemental sulfur from cysteine to produce alanine. It supplies the inorganic sulfur for iron- sulfur (Fe-S) clusters. Involved in both tRNA-processing and mitochondrial metabolism
