From: Resistance to aztreonam-avibactam due to a mutation of SHV-12 in Enterobacter

Secondary structure of SHV-12 and SHV-12R. The alignment of amino acid sequences and the prediction of secondary structures were performed using ENDscript 2 [30]. Secondary structure elements, α helixes, β sheets, and 310-helixes (representing by η), are indicated. β-strands are rendered as arrows, and strict β-turns are shown as TT letters
