Class 2 flagella operon. When transcribed, flhB is one of three flagella genes responsible for the generation of proteins that export flagellin to the flagella apparatus. The flagellin is then directly used in the synthesis of the structures’ basal body. Additionally, flhB directly transcribes the operon flhBAE.

flhB was use generated via PCR from the e coli strain DH5α and cloned into the vector pSB1C3. It is directly downstream of the class 1 flagella operons flhD and flhC. It also works in conjunction with fliL and fliH to make up the flagellin export system. This part can be used either to generate a flagella in an e. coli strain in which they are not already present, or to promote further formation of pre-existing flagella.
