Agreement Between Kcat And Local 1287

The comparison between kcat and kmaxvivo values (Figure 2 in the main text) could take into account two groups of enzymes: (i) faster enzymes in vitro (appear under the line y-x) and (ii) faster enzymes in vivo (appear above the y-x line). In order to study the link between alloster interactions and the rest between in vitro and in vivo levels, we downloaded all information on allostres inhibitors for the 132 enzymes analyzed from the BRENDA database (33) (complete data are displayed in the S1 dataset). Of all enzymes with faster in vitro activity, 85% (77 out of 85) have allotherence inhibitors, compared to 77% (34 of 44) of enzymes with faster in vivo activity. This enrichment is not statistically significant (p – 0.3 after Fisher`s exact test). A standard curve of product samples of different concentrations was created to maintain the relationship between the concentration and fluorescent intensity of the product. The standard product material, with a concentration of 2 m, was mixed with tampons under different conditions to make a number of concentrations. After mixing by the oscillating bladder, the concentrations were 0.0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0 m. After mixing, the fluorescent intensity was detected by a CCD camera. All the experimental conditions for fluorescence detection were the same as in our enzymatic reaction experiments. Figure 3a shows a single image taken during the calibration experiment. In this image, the flow ratio between the standard material and the buffer was 1:1. The fluorescent intensity along the direction of the width of the channel (direction y) is in Figure 3b.

The difference between liquid fluorescence and dark background was used as an effective fluorescent intensity. The entire calibration experiment was repeated three times to produce the calibration curve shown in the figure. 3c. Points represent the average value for each test, and the error bar represents the standard deviation. In order to completely characterize the reaction constants for different initial reaction times, we repeated this entire analysis process for different t2 values between 0.5 and 3.6 s with a resolution of 0.01 s. The results were obtained in Figure 1.
