Document Summary
Structural component of the cell, tubules, actins, and cytoskeleton elements. Sensors for environmental changes and mechanisms for relaying this information to the cell. Enzymes, catalysts for chemical reactions: gene regulation; activator or silencers that allow transcription to occur, modifiers that change the function of other protein; turning protein on and off. Components of transduction pathways that interpret those signals. Each protein has their own unique structure that allows it to carry out a specific function. Shape and structure ultimately leads to its function large donut-shaped structure with an active domain in the middle; glutamine synthetase. Smaller globular protein; signal insulin or the oxygen-carrying protein complex hemoglobin: y shaped; immunoglobulin protein that is necessary for recognizing antigens, viruses and bacteria, protein structure of binding domain and active domain. Protein are composed of the linear array of amino acid; creating the primary structure of the protein = a polypeptide.
