It may be self-serving, but I thought it also apt for the first article I review for Journal Club be my own. My paper, titled Multiple substitutions lead to increased loop flexibility and expanded specificity in Acinetobacter baumannii carbapenemase OXA-239, is the culmination of my undergraduate research. I was looking at a clinical variant of the beta-lactamase enzyme OXA-23 which has 3 amino acid substitutions.
