MetaCyc Pathway: assimilatory sulfate reduction II in Pontibacter actiniarum KMM 6156, DSM 19842

Add experiment(s):


Sulfate adenylyltransferase:

CA264_02540
CA264_02545
Adenylyl-sulfate reductase (glutathione) (in reverse):

CA264_02550
Sulfite reductase (ferredoxin) (in reverse):
sulfite + 8 H+ + 6 a reduced ferredoxin [iron-sulfur] cluster→hydrogen sulfide + 6 an oxidized ferredoxin [iron-sulfur] cluster + 3 H2O (EC 1.8.7.1)
CA264_02515

Candidate genes for each reaction are identified from best hits to MetaCyc; by matching EC numbers (which are assigned by TIGRFam, SEED, or best hits to KEGG); or by matching SEED roles to KEGG reactions to MetaCyc reactions. See the "Protein" tab of each gene for more information
