Part:BBa_K2973000
T7-RBS-β-Lactamase-No Signal peptide
This composite part consists of T7 Promoter(BBa_J64997) and T7 Terminator(BBa_K731721), Ribosomal Binding Site(BBa_B0034), CDS of β-lactamase without the 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 that way the detection of the enzyme.
