Definition of asd-S-ferredoxin

• Curated sequence Q8TPT3: L-aspartate semialdehyde sulfurtransferase iron-sulfur subunit
• Curated sequence 8499492: Homocysteine formation from aspartate semialdehyde (NIL/ferredoxin component)
• Predicted: UniProt sequence A6UQ02: SubName: Full=4Fe-4S ferredoxin iron-sulfur binding domain protein {ECO:0000313|EMBL:ABR54574.1};
• Comment: The NIL/ferredoxin component is MA1822 or DvMF_0262 (see PMID:25315403 and PMC5764234). In Methanococcus, the persulfide component (MEVAN_RS03425, A6UQ02) is diverged but is in a conserved operon with the sulfurtransferase component.
