β-Lactamase-No-signal-peptide

β-lactamase (EC 3.5.2.6) is a small monomeric enzyme(29kDa) that is produced by bacteria and gives them resistance to antibiotics with β-lactam ring because of its ability to hydrolyze the amide bond in the β-lactam ring. This ability can be exploited in order to use β-lactamase as a protein reporter by providing the enzyme with its chromogenic substrate Nitrocefin. Nitrocefin is a chromogenic cephalosporin first reported in 1972 as a novel and straightforward substrate used to detect bacteria resistant to β-lactam antibiotics. Normally, a nitrocefin solution has a yellow color, but after its hydrolysis by β-lactamase, the color of the solution turns red, allowing in that way the detection of the enzyme.
