Often people in the electrical industry learn about the requirements for ground-fault protection in electrical service equipment by the “school of hard knocks” when a ground-fault in a service not equipped with a ground-fault protection device endures the forces of a destructive ground-fault leading to a total burndown of their electrical service, or equipment, to their facilities. It has concluded that both GFP and YFP are interlinked proteins with different characteristics and uses.Ground-fault protection of equipment and ground-fault circuit interrupters for personnel are essential to safety. Hence, the most common donor fluorescent protein is a monomeric cyan fluorescent protein which another GFP derivative. The importance of YFP in molecular biology is to serve as the acceptor for genetically coded Forster resonance energy transfer sensors. Therefore, YFP absorbs green light at 514 nm wavelength while emitting yellow color light 527 nm. This results in pi electron stacking interactions between the substituted tyrosine and the chromophore. It is a color which is a mutant accomplished by the T203Y mutation. The specific properties of these improved versions are that they have chloride sensitivity which is reduced and it has a faster maturation and increased brightness due to quantum yield. Yellow fluorescent protein has three versions, Venus, citrine, and Yet. The applications of YFP are same as GFP in molecular biology. It has two different peaks emission peak at 527 nm and its excitation peak at 515 nm. YFP refers to the Yellow Fluorescent Protein which is a mutant of the originally derived from GFP from the jellyfish Aequorea Victoria. An event refers to the emission of photons. QY refers to the number of times an event occurs when a radiation-induced process takes place per photon. The quantum yield of the green fluorescent protein is 0.79. 509 nm in the visible region is the lower green part. It means, this protein completely absorbs blue light at 475 nm or the 395 nm light in the long UV range and emits green light at 509 nm. It shows an excitation peak at 395 nm wavelength and an emission peak at 509 nm wavelength. Noncovalent relations of the chromophore with the neighboring molecules increase its spectral properties.įluorescent proteins have two peaks which are an excitation peak and an emission peak. This chromophore is packed inside the beta-barrel structure, protecting the chromophore from quenching through paramagnetic oxygen, water dipoles or cis-trans isomerization. The part of the protein that makes it fluorescent is developed from the conjugation of the central chain atoms, Tyr66, Ser65, and Gly67, forming the highly conjugated, planar chromophore in the presence of oxygen. Protein folds to form the shape of a beta barrel. This protein is composed of 238 amino acids which are attached with each other through a peptide bond, and the size of the protein is 26.7 kDa.

The main characteristic of GFP is that when it is exposed to blue ultraviolet light, it shows a green fluorescence.

GFP or Green Fluorescent Protein is bioluminescent polypeptide protein naturally found in marine animals such as jellyfish Aequorea victoria. It is a process which describes the energy transfer between 2 chromophores. They are also called EET or RET electronic energy transfer and resonance energy transfer. FRET stands for Fluorescent Resonance energy transfer.

YFP proteins are used as acceptors for FRET sensors. GFP helps in measuring and indicating whether a gene has been expressed by an organism cell or population.

Reporter genes are used by scientists and researchers to attach to another gene which they are studying. GFP is beneficial in cell and molecular biology.
