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
A	PF22613	Transketolase-like TK C-terminal domain (Transketolase_C_1)	Transketolase-like TK C-terminal domain	This entry represents the C-terminal domain found in transketolase and transketolase-like enzymes [1-5], such as pyruvate dehydrogenase E1 component (OPD1) [4].	Domain
