MetaCyc Pathway: biotin biosynthesis from 8-amino-7-oxononanoate I in Pectobacterium carotovorum WPP14

Add experiment(s):


Adenosylmethionine--8-amino-7-oxononanoate transaminase:
(8S)-8-amino-7-oxononanoate + S-adenosyl-L-methionine→(7R,8S)-diaminononanoate + S-adenosyl-4-methylsulfanyl-2-oxobutanoate (EC 2.6.1.62)
HER17_RS09850
HER17_RS13465
Dethiobiotin synthase:
(7R,8S)-diaminononanoate + ATP + CO2→dethiobiotin + ADP + 3 H+ + phosphate (EC 6.3.3.3)
HER17_RS10730
HER17_RS13445
Biotin synthase:
dethiobiotin + H+ + 2 a reduced [2Fe-2S] ferredoxin + S-adenosyl-L-methionine + a sulfurated [sulfur carrier]→4,5-secobiotin + 5'-deoxyadenosine + L-methionine + 2 an oxidized [2Fe-2S] ferredoxin + an unsulfurated [sulfur carrier] (EC 2.8.1.6)
HER17_RS13460
Biotin synthase:
4,5-secobiotin + S-adenosyl-L-methionine→biotin + 5'-deoxyadenosine + L-methionine + H+ (EC 2.8.1.6)
HER17_RS13460

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
