YgfZ is a folate-binding protein involved in regulating the level of ATP-dnaA and in the modification of some tRNAs [1,2]. It consists of a folate-binding domain at the N-terminal (Pfam:PF01571) and a six-stranded antiparallel beta-barrel at the C-terminal, represented in this entry, with identical topology found at the C-terminal of elongation factors Tu and eEF-1alpha and in the gamma subunit of the initiation factor eIF2 [1].
