The invention deals with mutated truncated mt-pfkA gene encoding shorter fragment of 6-phosphofructo-1-kinase (PFK1), with no need for phosphorylation of the protein molecule for activation, that is not significantly inhibited by citric acid and/or its salts and ATP molecules. Active 49-52 kDa fragment encoded by mt-pfkA gene, retains positive regulatory properties of the native protein and is activated in the presence of specific activators, while citric acid and ATP, important metabolites that function as feed back inhibitors in higher organisms do not reduce its activity. The invention deals with the use of modified shorter fragment in biotechnological processes for fabricating primary and secondary metabolites.
