CRYSTAL STRUCTURES OF THE PLP- AND PMP-BOUND FORMS OF BTRR, A DUAL FUNCTIONAL AMINOTRANSFERASE INVOLVED IN BUTIROSIN BIOSYNTHESIS.
Overview
The aminotransferase (BtrR), which is involved in the biosynthesis of, butirosin, a 2-deoxystreptamine (2-DOS)-containing aminoglycoside, antibiotic produced by Bacillus circulans, catalyses the pyridoxal, phosphate (PLP)-dependent transamination reaction both of, 2-deoxy-scyllo-inosose to 2-deoxy-scyllo-inosamine and of, amino-dideoxy-scyllo-inosose to 2-DOS. The high-resolution crystal, structures of the PLP- and PMP-bound forms of BtrR aminotransferase from, B. circulans were solved at resolutions of 2.1 A and 1.7 A with, R(factor)/R(free) values of 17.4/20.6 and 19.9/21.9, respectively. BtrR, has a fold characteristic of the aspartate aminotransferase family, and, sequence and structure analysis categorises it as a member of SMAT, (secondary metabolite aminotransferases) subfamily.
