beta-lactamase F. enterobacter cloacae - Physico-chemical Properties
| Melting Point | 121-126°C |
| Appearance | powder |
| Color | white |
| Merck | 14,7093 |
| Storage Condition | 2-8°C |
| Physical and Chemical Properties | Penicillinase is a white powder. Dissolved in water, the enzyme solution is easily inactivated. The dry product is stable at room temperature, and the freeze-dried product can be stable for one week at 2~8 ℃. The β-lactam ring that acts on penicillin converts penicillin into sterile active penicillin keto acid. 1h after intramuscular injection, the effect of penicillin quickly failed. The effect is maintained for at least 4 days, thereby subsiding the already produced penicillium allergy symptoms. |

beta-lactamase F. enterobacter cloacae - Nature
Open Data Verified Data
The enzyme extracted from the culture filtrate of Bacillus cereus in this strain was white powder and dissolved in water. The dry product was stable at room temperature, and the enzyme solution was easily inactivated. The freeze-dried product can be stable for one week at 2~8 ℃. The relative molecular mass is about 50000. Action on the B- lactam ring of penicillin results in conversion of penicillin to penicillin ketoacid (penicillo-ic acid) with no antibacterial activity. After the intramuscular injection of th occurs, so that the rapid failure of penicillin, the role of at least 4 days, so as to resolve the allergic symptoms of penicillin has been produced.
