It was found that the P. mirabilis 5127-1 bacteria secretes metalloproteinase in the medium in two isoforms (52 and 50 kDa). It was established that proteinase synthesis is completely suppressed during the growth of bacteria on synthetic media, as well as in the presence of LB glucose in the medium. It was demonstrated that addition of urea in the medium results in an increase of the culture productivity in the proteinase synthesis. Maximal culture productivity in the proteinase synthesis was found in the medium with natural urine. During the growth of bacteria on artificial urine, proteinase appeared in the medium only after 12 hours of growth as a single isoform.</p>","PeriodicalId":77187,"journal":{"name":"Izvestiia Akademii nauk.

It has been found that a 1-hour exposure to a combined magnetic field with resonance parameters for potassium ions has almost no effect on the activity of proteinases, but it decreases the amylolytic activity. It has been noted that the activity of proteases and glycosidases is lower under hypomagnetic conditions.
