A1492 and A1493 Explanation:

A1492 and A1493 are two universally conserved bases in 16S rRNA that are critical for codon - anticodon recognition. These insert into the minor groove, between the codon and anticodon and stabilize the interaction. In the 30S A site of rRNA, A1493C or any substitution of G530 or A1492 leads to the complete loss of translation activity. Whereas, A1493U and A1493G decrease translation activity by >20-fold.
