Green fluorescent protein (GFP), originally isolated from the jellyfish Aequorea victoria (PDB entry 1ema), fluorsceses green (509nm) when exposed to blue light (395nm and 475nm). It is one of the most important proteins used in biological research because it can be used to tag otherwise invisible gene products of interest and thus observe their existence, location and movement.

GFP is a beta barrel protein with 11 beta sheets. It is a 26.9kDa protein made up of 238 amino acids. The chromophore, responsible for the fluorescent properties of the protein, is buried inside the beta barrel as part of the central alpha helix passing through the barrel. The chromophore forms via spontaneous cyclization and oxidation of three residues in the central alpha helix: -Thr65 (or Ser65)-Tyr66-Gly67. This cyclization and oxidation creates the chromophore's five-membered ring via a new bond between the threonine and the glycine residues.<ref>PMID:8703075</ref>

משמעות הדבר היא שמתרחשת מוטציה אחת כל כשלושת אלפים נוקלאוטידים המתרכבים למולקולת ה-DNA הנוצרת. קצב המוטציות הגבוה גורם לכך שהחומר התורשתי של הנגיף משתנה כמעט עם כל הדבקה. עקב כך, מוטציות שמתרחשות במהלך פעולתו של אנזים RT גורמות לשינוי החומר הגנטי של הנגיף. דבר זה מאפשר לנגיף "להתחמק" מן המערכת החיסונית של המאכסן ולפתח עמידות נגד תרופות אנטי-ויראליות, ולכן פיתוח תרופות נגד הנגיף נתקל בקשיים רבים.

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
