Part:BBa_K819009

Weak cheZ generator

CheZ is a significant protein in E.coli chemotaxis pathway. CheZ can prevent the cells from tumbling around and keep them moving. Deletion of CheZ or repression of CheZ expression can result in a non-motile phenotype.
CheZ was placed under a weak promoter BBa_J23112. This part expresses CheZ protein weakly and induces weak mobility in delta CheZ E.coli strain.
The photo below shows CheZ's influence on cell motility
