ureE, nickel-binding protein from Sporosarcina pasteurii DSM33

ureE encodes for a nickel-binding protein involved in the assembly of the urease metallocentre in S. pasteurii DSM33 (Ciurli et al., 2002; Remaut et al., 2001). The urease is crucial for catalyzing the hydrolysis of urea into ammonia and carbon dioxide, a key step in the process of microbially induced calcite precipitation (MICP).

Usage and Biology

Microbiologically Induced Calcite Precipitation (MICP) involves hydrolyzing urea into ammonia and carbonate ions, raising pH to form calcium carbonate precipitates (Sarayu et al., 2014). This process can also precipitate heavy metals like cadmium and remove them from the water (Qasem et al., 2021). By introducing urease-related genes (ureE) from S. pasteurii into E. coli, E. coli can be engineered to be a heavy metal remover.
