    The nucleotide (nt) sequence of the cholesterol oxidase (Cho)-encoding gene (choB) cloned from Brevibacterium sterolicum ATCC21387 was determined. The sequence contained an open reading frame with a G + C content of 64.9 mol% that would encode a protein of 552 amino acids (aa). Comparison of the nt sequence of choB and deduced aa sequence to those of the Cho-encoding gene (choA) of Streptomyces sp. strain SA-COO showed identities of 64% and 58%, respectively. N-terminal aa sequence analysis of the extracellular enzyme of B. sterolicum confirmed that the mature enzyme consisted of 507 aa with a predicted Mr of 54,902, and was preceded by a 45-aa signal sequence.
