Sequence Changes

Date	Affected Features	Start Coordinate of Change	End Coordinate of Change	Type of Change	Old Sequence	New Sequence
2011-02-03	YJR103W	622414	622414	Insertion		C
	A single C nucleotide was inserted very near the 3' end of ORF URA8/YJR103W, altering its coding sequence. The start and most of the reading frame remain the same, but the C-terminus has changed and the annotated protein is now 14 amino acids longer.

	Nucleotide changes within the coding region of YJL171C resulted in an altered protein sequence. The start, stop, and reading frame remain the same, but protein residue 366 is now Lysine rather than Leucine, residue 371 is now Alanine rather than Arginine, and residue 374 is now Lysine rather than Asparagine.

	Nucleotide change(s) in the coding region of YJR107W resulted in an altered protein sequence. The start, stop, and reading frame remain the same, but protein residue 14 is now Proline rather than Leucine, and residue 66 is now Glycine rather than Proline.
