Moreover, a new line appears at about 117 [cm.sup.-1] for 0.95BT-0.05PZN (indicated by arrow), which may be evidence of a structural change associated with the
A-site symmetry change.
Aminoglycoside antibiotics exert their antibacterial activity by binding to 16S ribosomal RNA at the tRNA acceptor
A-site (aminoacyl site), and affect the ability of the ribosome to decode mRNA correctly during protein synthesis [3].
Tetracycline, a broad-spectrum antibiotic, binds primarily at the
A-site as well as at several secondary sites.
Indeed, rather than negative feedback from B sites upon
A-site output, we see positive amplification of B-site output by
A-site surplus.
In 1993-94, the school piloted a new program in which grade information compiled in grade2 is transferred directly to
A-SITE, a mainframe computer system that sends data to the district head office for report card generation.
