					Additional FieldsIn cases where the amino acid sequence is collected rather than the nucleotide sequence, the field SEQ_NUC might be replaced with SEQ_AA, which is the nucleotide sequence, expressed in an amino acid sequence:

					However using the amino acid sequence does not give the same detail of data as the nucleoside sequence: wobbles in the nucleoside sequence can either complicate the reading and alignment of the amino acid sequence or the wobbles can be lost and silent mutations are lost.
