Provided is a method of preparing a granular feed additive. When the method of preparing a granular feed additive according to one exemplary embodiment is used, it is possible to prepare a granular feed additive including a high content of basic amino acids while preventing hygroscopicity and agglomeration caused by the basic amino acids. In addition, since the method of preparing a granular feed additive according to one exemplary embodiment may omit a process of using hydrochloric acid, which is generally used to neutralize basic amino acids, it is possible to simplify the process and to solve process problems caused by the use of hydrochloric acid.

The present invention relates to a novel phosphoenolpyruvate carboxylase variant and a method of producing 5'-inosinic acid using the same. The phosphoenolpyruvate carboxylase variant is obtained by substituting one or more amino acids in the amino acid sequence constituting phosphoenolpyruvate carboxylase to change the activity of the protein, and a recombinant microorganism comprising the phosphoenolpyruvate carboxylase variant is capable of efficiently producing 5′-inosinic acid.
