An enzyme is a protein that facilitates certain cell processes

The G protein dissociates and one subunit interacts with and activates an enzyme - adenylate cyclase- which converts ATP into a second messenger - cyclic AMP (cAMP) - in the cell. cAMP activates protein kinase A (PKA) which phosphorylates proteins at specific Ser or Thr side chains. ABSTRACT. The eukaryotic endoplasmic reticulum (ER) membrane contains essential complexes that oversee protein biogenesis and lipid metabolism, impacting nearly all aspects of cell physiology. The ER membrane protein complex (EMC) is a newly described transmembrane domain (TMD) insertase linked with various phenotypes, but whose clients and cellular responsibilities remain incompletely understood. Many enzymes acquire full enzymatic activity as they spontaneously fold into their characteristic three-dimensional forms. In contrast, other enzymes are synthesized as inactive precursors that are subsequently activated by cleavage of one or a few specific peptide bonds. The inactive precursor is...

In the cell, the introns are removed by special enzymes, which recognize specific sequences. These enzymes cut and re-join the coding regions for translation into protein.
Iron is necessary for the formation of certain proteins and enzymes. Hemoglobin (HE-mo-globin), which is the oxygen-carrying protein in the blood, is one such iron-dependent protein. Iron deficiency can lead to anemia, a lack of oxygen in the blood, which in turn can lead to fatigue and other complications.

Enzymes are proteins that act as catalysts within living cells. Enzyme - Substrate Complex. Enzymes involved in synthesis reactions have an active site which combines with the two or more reactants, aligning them in such a way that they combine to form the required product.Enzymes are sensitive to heat and are denatured by excess heat or cold, i.e. their active site becomes permanently warped, thus the enzyme is unable to form an enzyme substrate complex. This is what happens when you fry an egg, the egg white (augmentin, a type of protein, not an enzyme), is denatured. Without proteins, living things would not exist. Proteins are involved in every aspect of every living thing. Many proteins provide structure to cells; others bind to and carry important molecules throughout the body. Some proteins are involved in reactions in the body when they serve as enzymes. Still others are involved in muscle contraction or […]
