Disease

NFS1_HUMAN Severe neonatal lactic acidosis due to NFS1-ISD11 complex deficiency.

Function

NFS1_HUMAN Catalyzes the removal of elemental sulfur from cysteine to produce alanine. It supplies the inorganic sulfur for iron-sulfur (Fe-S) clusters. May be involved in the biosynthesis of molybdenum cofactor.[1]
