In order to utilize the less useful shortened cellulose from wastepaper as the raw material to produce bacterial cellulose(BC) in situ, ECUST iGEMers developed “paper transformer”.

HlyD

The α-hemolysin secretion pathway has mainly been reported in uropathogenic E. coli. The secretory machinery of this pathway consists of three components: HlyB, an ATP-binding cassette (ABC transporter); HlyD, a membrane fusion protein; and TolC, an outer membrane protein. HlyB and HlyD have been generally considered strain specific proteins, TolC, in contrast, is a component of multiple trans-membrane systems in many microorganisms. Thus, co-expression of HlyB/D is often performed to facilitate the extracellular translocation of proteins utilizing the α-hemolysin secretion pathway during expression in host strains other than uropathogenic E. coli.
