Abstract: The present invention relates to a midsole which reduces a load applied to a knee, and more particularly, to a midsole which reduces a load applied to a knee, in which a first soft portion and a second soft portion are disposed at a front inner side and a rear inner side so as to allow an inner knee to relatively and smoothly move, thereby reducing impact and load concentrated on an inner knee joint, and expecting improved exercise capacity.

Abstract: Disclosed herein are ammonia-specific 5?-XMP aminase mutants and a method for preparing the same. A mutation is introduced into the active site of glutamine-dependent catalysis in 5?-XMP aminase. The resulting 5?-XMP aminase mutant is devoid of the glutamine-dependent activity and specifically reacts with external ammonia in converting 5?-XMP into 5?-GMP. Thus, the ammonia-specific 5?-XMP aminase mutant is stabler within cells compared to the wild type, and can be useful in the industrial conversion of 5?-XMP into 5?-GMP.

Abstract: Provided are a promoter including at least one polynucleotide selected from the group consisting of SEQ ID NOS: 1 to 7, an expression cassette including the same, a vector including the expression cassette, a host cell including the vector, and a method of expressing a gene using the host cell.
