In. Sidorenkov et al., CLONING AND EXPRESSION OF BACILLUS-STEAROTHERMOPHILUS NEUTRAL PROTEINASE GENE IN BACILLUS-SUBTILIS, Molecular biology, 29(3), 1995, pp. 286-288
A gene library of the thermophilic bacterium Bacillus stearothermophil
us was made in a plasmid vector, and the gene of thermostable metallop
roteinase was cloned. Restriction mapping proved it to be close to the
B. stearothermophilus metalloproteinase T gene cloned earlier. The cl
oned expressed in B. subtilis, and its protein product was characteriz
ed in terms of heat stability and temperature optimum.
