Words similar to penicillins
Example sentences for: penicillins
How can you use “penicillins” in a sentence? Here are some example sentences to help you improve your vocabulary:
When penicillins were used as substrates, the Tyr228 mutants exhibited 3- to 13-fold increased K m values and < 2-fold changes in k cat , as compared to the values ascertained using wild-type L1 (Table 4).
Only when Ser224 was replaced with an Asp residue was there significant increases in the observed K m value for 6 of the 9 substrates tested, and the largest changes were exhibited when the penicillins were used as substrates.
As with the I164A mutant, the changes in K m and k cat for the penicillins and carbapenems were relatively small, as compared with the values obtained with the cephalosporins (Table 4).
Generally, the S224A and S224K mutants exhibited small changes in K m and k cat , while the S224D mutant yielded 20- to 40-fold increased values for K m and >10-fold decreases in k cat when using the penicillins as substrates.
On the other hand, the K m and k cat values for the I164A mutant when the penicillins or carbapenems were used as substrates were very similar to those numbers exhibited by wild-type L1 (Tables 4and 5).
