Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF00456 Transketolase_N Transketolase, thiamine diphosphate binding domain 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 aspects in their mechanism of catalysis. PFAM PF00456
A PF02779 Transket_pyr Transketolase, pyrimidine binding domain Domain This family includes transketolase enzymes, pyruvate dehydrogenases, and branched chain alpha-keto acid decarboxylases. PFAM PF02779
A PF02780 Transketolase_C Transketolase, C-terminal domain Domain The C-terminal domain of transketolase has been proposed as a regulatory molecule binding site [2]. PFAM PF02780
