Class I enzymes attach the amino acid to the 2’-OH of the tRNA and are generally monomeric. Class II enzymes attach the amino acid to the 3’-OH of the tRNA and are typically dimeric or tetrameric.The amino acids for which the Class I synthetases are specific tend to be larger and more hydrophobic than those for Class II synthetases.

The ‘Wallace rule’ (Lay Thein & Wallace 1986) is used to determine the appropriate stringency wash temperature: 

Tm = 4 × (number of GC base pairs) + 2 × (number of AT base pairs
