What is a GI number?

• A unique number that is given to every submitted sequence. If the sequence is changed, it receives a new GI number.
• A unique number that is given to every submitted sequence. If the sequence is changed, a suffix is added to the number. This makes it easy to track changes that occurred to a sequence.
• The Genomic Isoform number is given to every type of enzyme. This number provides easy access to enzymes from different organisms that have the same or similar function.
• A unique number that is given to every submitted sequence. If the sequence is changed, it retains this number. This makes it easy to track changes that occurred to a sequence.
