Fig. 4From: The human transketolase-like proteins TKTL1 and TKTL2 are bona fide transketolasesBinding of thiamine backbone to the enzyme. The residues involved in hydrogen bonds, hydrophobic interactions and stacking interactions in (a) TKT and (b) TKTL1 are shown. The residues indicated by asterisks have been implicated in catalysisBack to article page
