We are happy to announce that we have successfully created four BioBricks over the course of this summer! Among them is one intein BioBrick, the Ssp GyrB Split Intein which will surely be useful in many future projects.

  • K1483000: α-N-Acetylgalactosamindase

    The α-N-acetylgalactosamindase (NAGA) is an enzyme from Elizabethkingia meningoseptica capable of cleaving off N-acetlygalactosamine from A-group blood antigens (Figure 1).

  • K1483001: Endo-β-Galactosidase

    The endo-β-galactosidase - also called EABase - is an enzyme from Clostridium perfringens which can cleave off trisaccharides from the A- and B-group blood antigens which leaves behind a precursor of the H-antigen (Figure 2).

  • K1483002: α-Galactosidase

    This Bacteroides fragilis enzyme α-galactosidase (aGAL) cleaves off B-group blood antigens from erythrocytes thereby creating H-antigens (Figure 3).

  • K1483003: Ssp GyrB Split Intein

    This protein naturally occurs in Synechocystis sp. PCC6803. The gyr B split intein is a bacterial intein with a 6 aminoacid long C-intein and a 150 aminoacid long N-intein and can be used e.g. to fuse two proteins (Figure 4).
