The crucial steps of cellular photoperception are characterized and followed in real time by laser spectroscopy down to a few tens of femtoseconds. The photoactive proteins studied here are involved in major natural processes such as vision (bacteriorhodopsin used as a model of retinal chromoproteins), microorganism photomotility (photoactive yellow protein and oxyblepharismin binding protein) and plant phototropism (cryptochrome). It is also shown that the green fluorescent protein (GFP) can be used, upstream from genic therapy, as a temporal probe of cytoplasmic soly. of antibody fragments with which it is fused.Proteins Role: BSU (Biological studyunclassified)PEP (Physicalengineering or chemical process)PRP (Properties)BIOL (Biological study)PROC (Process) (OBIP (OxyBlepharismin bInding Protein); cellular photoperception and photoactive proteins); Proteins Role: BSU (Biological studyunclassified)PEP (Physicalengineering or chemical process)PRP (Properties)BIOL (Biological study)PROC (Process) (PYP (photoactive yellow protein); cellular photoperception and photoactive proteins); Laser spectroscopy; Photochemistry; Retina (cellular photoperception and photoactive proteins); Bacteriorhodopsins; Photoreceptors Role: BSU (Biological studyunclassified)PEP (Physicalengineering or chemical process)PRP (Properties)BIOL (Biological study)PROC (Process) (cellular photoperception and photoactive proteins); Proteins Role: BSU (Biological studyunclassified)PEP (Physicalengineering or chemical process)PRP (Properties)BIOL (Biological study)PROC (Process) (chromoproteins; cellular photoperception and photoactive proteins); Light (perception; cellular photoperception and photoactive proteins)review photoreceptor photoperception photoactive protein chromophore lightunclassified)PEP (Physicalengineering or chemical process)PRP (Properties)BIOL (Biological study)unclassified)PEP (Physicalengineering or chemical process)PRP (Properties)BIOL (Biological study)unclassified)PEP (Physicalengineering or chemical process)PRP (Properties)BIOL (Biological study)Cellular photoperception and photoactive proteinstext::journal::journal article::research article
