ureA, urease subunit gamma from Sporosarcina pasteurii DSM33
ureA encodes for a urease subunit gamma in S. pasteurii DSM33, which is one of the three essential subunits (gamma, beta, and alpha) that together form the active urease enzyme complex (Moersdorf et al., 1994). This enzyme 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 genes (ureA) from S. pasteurii into E. coli, E. coli can be engineered to be a heavy metal remover.
