MetaCyc Pathway: pentose phosphate pathway (non-oxidative branch) I in Salmonella enterica subsp. enterica serovar Typhimurium str. MS1868

Ribose-5-phosphate isomerase (in reverse):
D-ribulose 5-phosphate→D-ribose 5-phosphate (EC 5.3.1.6)

Ribulose-phosphate 3-epimerase:
D-ribulose 5-phosphate→D-xylulose 5-phosphate (EC 5.1.3.1)

Transketolase (in reverse):
D-ribose 5-phosphate + D-xylulose 5-phosphate→D-sedoheptulose 7-phosphate + D-glyceraldehyde 3-phosphate (EC 2.2.1.1)

Transaldolase:
D-sedoheptulose 7-phosphate + D-glyceraldehyde 3-phosphate→D-erythrose 4-phosphate + β-D-fructofuranose 6-phosphate (EC 2.2.1.2)

Transketolase:
D-erythrose 4-phosphate + D-xylulose 5-phosphate→β-D-fructofuranose 6-phosphate + D-glyceraldehyde 3-phosphate (EC 2.2.1.1)

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
