UniProtKB - Q312S2 (ISLA_DESAG)
Protein
Isethionate sulfite-lyase
Gene
islA
Organism
Desulfovibrio alaskensis (strain G20) (Desulfovibrio desulfuricans (strain G20))
Status
Functioni
Involved in an anaerobic respiration pathway that converts the sulfonate isethionate (2-hydroxyethanesulfonate) to ammonia, acetate and sulfide. Catalyzes the radical-mediated C-S bond cleavage of isethionate (2-hydroxyethanesulfonate) to form sulfite and acetaldehyde.1 Publication
Catalytic activityi
- This reaction proceeds in the forward1 Publication direction.
: alkanesulfonate degradation Pathwayi
This protein is involved in the pathway alkanesulfonate degradation, which is part of Organosulfur degradation.1 PublicationView all proteins of this organism that are known to be involved in the pathway alkanesulfonate degradation and in Organosulfur degradation.
