A, B, C, D	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
A, B, C, D	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
A, B, C, D	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 ...	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.	Domain
