"High expression" promoter

This "high expression" promoter is taken from strain Brevibacillus brevis NBRC 100599. It codes for an enzyme, phosphoribosylaminoimidazole carboxylase catalytic subunit (BAH41514.1), which is involved in nucleotide biosynthesis, particularly in purine biosynthesis. It catalyzes the conversion of AIR (5’-phosphoribosyl-5-aminoimidazole) into CAIR (5’-phosphoribosyl-4-carboxy-5-aminoimidazole).
