PF02779 | Transketolase, pyrimidine binding domain (Transket_pyr) | Transketolase, pyrimidine binding domain | This family includes transketolase enzymes, pyruvate dehydrogenases, and branched chain alpha-keto acid decarboxylases. | Domain | |
PF02780 | Transketolase, C-terminal domain (Transketolase_C) | Transketolase, C-terminal domain | The C-terminal domain of transketolase has been proposed as a regulatory molecule binding site [2]. | Domain | |
PF00456 | Transketolase, thiamine diphosphate binding domain (Transketolase_N) | Transketolase, thiamine diphosphate binding domain | This family includes transketolase enzymes EC:2.2.1.1. and also partially matches to 2-oxoisovalerate dehydrogenase beta subunit Swiss:P37941 EC:1.2.4.4. Both these enzymes utilise thiamine pyrophosphate as a cofactor, suggesting there may be common ... | Domain |
