Q1 - What is the name of the protein?
The given protein code is 1ZXX. The name of this protein is phosphofructokinase which is
shortly known as Pfk from lactobacillus delbrueckii
Q2 - What does the protein do?
The enzyme which is named as phosphofructokinase controls the maximum quantity of
glucose which are generally produced from the glycolysis (Villalobos et al. 2016). Glycolysis
is a process where it generally converts fructose-6-phosphate into D fructose 1,6 biphosphate
with the help of ATP. The equation is as follows.
D fructose 6 phosphate + ATP  D fructose 1, 6 biphosphate + ADP
In the process of D frustose 6 phosphate phosphorylation ATP is the one who provides
adequate amount of phosphate group to complete this process. In the mean time it performed
as negative loop to subpress the action of the Pfk only when adequate amount of energy are
producing which a cell can use to do their action (Gong et al. 2016).
Q3 - What are the structural features of the protein?
Pfk is considered as a monomer. It is primarily made up of amino acids which forms a
peptide chain.
