>cd01400 6PGL 6PGL: 6-Phosphogluconolactonase (6PGL) subfamily; 6PGL catalyzes the second step of the oxidative phase of the pentose phosphate pathway, the hydrolyzation of 6-phosphoglucono-1,5-lactone (delta form) to 6-phosphogluconate
6PGL is thought to guard against the accumulation of the delta form of the lactone, which may be toxic through its reaction with endogenous cellular nucleophiles.
>cd00458 SugarP_isomerase SugarP_isomerase: Sugar Phosphate Isomerase family; includes type A ribose 5-phosphate isomerase (RPI_A), glucosamine-6-phosphate (GlcN6P) deaminase, and 6-phosphogluconolactonase (6PGL)
RPI catalyzes the reversible conversion of ribose-5-phosphate to ribulose 5-phosphate, the first step of the non-oxidative branch of the pentose phosphate pathway. GlcN6P deaminase catalyzes the reversible conversion of GlcN6P to D-fructose-6-phosphate (Fru6P) and ammonium, the last step of the metabolic pathway of N-acetyl-D-glucosamine-6-phosphate. 6PGL converts 6-phosphoglucono-1,5-lactone to 6-phosphogluconate, the second step of the oxidative phase of the pentose phosphate pathway.

1.1.31 from EC), Glucosamine-6-phosphate isomerase (3.5.99.6 from EC), and Galactosamine-6-phosphate isomerase. 6-Phosphogluconolactonase is the enzyme responsible for the hydrolysis of 6-phosphogluconolactone to 6-phosphogluconate, the second step in the pentose phosphate pathway. Glucosamine-6-phosphate isomerase (or Glucosamine 6-phosphate deaminase) is the enzyme responsible for the conversion of D-glucosamine 6-phosphate into D-fructose 6-phosphate []. It is the last specific step in the pathway for N-acetylglucosamine (GlcNAC) utilization in bacteria such as Escherichia coli (gene nagB) or in fungi such as Candida albicans (gene NAG1).; GO: 0005975 carbohydrate metabolic process; PDB: 3CSS_A 3CH7_A 1Y89_B 3TX2_A 2BKX_B 2BKV_B 3E15_B 1HOR_B 1JT9_A 1HOT_A ....
>PF04198 Sugar-bind: Putative sugar-binding domain; InterPro: IPR007324 This probable domain is found in bacterial transcriptional regulators such as DeoR and SorC
One of these proteins, Q8U7I7 from SWISSPROT, has an N-terminal helix-turn-helix IPR000792 from INTERPRO that binds to DNA. This domain is probably the ligand regulator binding region. SorC is regulated by sorbose and other members of this family are likely to be regulated by other sugar substrates.; GO: 0030246 carbohydrate binding; PDB: 3KV1_A 3EFB_C 2W48_A 3BXH_A 3BXE_A 2OKG_A 3BXF_A 3BXG_A 2R5F_A 2O0M_A ....
