Multiple sequence alignment of YgjG to known class III PLP-dependent aminotransferases. The alignment was performed with ClustalW http://www.ebi.ac.uk/clustalw The residues that are identical in all the displayed sequences are marked by asterisks, conserved residues are marked by dots and the four invariant residues (G, D, K and R) proposed for aminotransferases are bold and boxed. Abbreviations are: ArgD, acetylornithine delta-aminotransferase (ATase) (AAC76384); GoaG, 4-aminobutyric acid ATase (AAC74384); SpuC, putrescine:pyruvate ATase [13]; BioA, 7,8-diaminopelargonic acid synthetase (AAC73861).
