Kinetic Mechanisms and Parameters for Bi-Bi Reactions
Description
Discriminates between sequential and ping-pong mechanisms and estimates the kinetic parameters.
Usage
bibi(data, unit_a = "mM", unit_b = "mM", unit_v = "ua", vice_versa = FALSE)
Arguments
data |
either a dataframe or the path to a text file containing the data (see details). |
unit_a |
concentration unit for substrate A. |
unit_b |
concentration unit for substrate B. |
unit_v |
velocity unit. |
vice_versa |
logical. When FALSE the variable substrate is A. If TRUE, then the variable substrate is B. |
Details
Either the txt file or the dataframe containing the data must conform to the following format: a table with three columns and as many rows as conditions were assessed. The first and second columns are named 'a' and 'b' and they give the concentrations for substrate A and B, respectively. The third column, named 'rate', provides the assessed rates.
Value
A list with three elements: (i) a character vector giving the kinetic parameters Vmax, KiA, Km_A and Km_B values; (ii) a numeric vector giving the apparent inverse of Vmax for each concentration of substrate B (intercepts of primary representation); and (iii) a numeric vector giving the apparent specificity constant for each concentration of substrate B (slopes from primary representations).
Examples
