formation of ionic bonds, last part of the protein folding pathway; compaction of the protein, a biological process that occurs in it's natural environment, a folding accessory protein; binds unfolded proteins by "sheltering" exposed non-polar regions, a folding accessory protein; ensures that proteins do not de-nature at high temperatures, the loss of protein function (as well as structure), can be renatured "in vitro", a protein in which all the subunits are the same, a protein in which the subunits are different, the number of AA's on one alpha chain in hemoglobin, the number of AA's on one beta chain in hemoglobin, a prosthetic group (polypyrole ring) that binds Fe, has 4 bonding points, the number of bonding points that Fe requires, shields the Fe in hemoglobin in the +2 state of oxygen uptake, an oxygen carrying molecule, forms a sigmoidal oxygen binding curve, found in the vascular system, 50% saturation @ 3kPa, an oxygen carrying molecule, forms a hyperbolic oxygen binding curve, found in the musculature for uptake, 50% saturation @ .2kPa, the binding of one site affects binding at another site, the co-operative binding of hemoglobin and its dependency on protons and carbon dioxide concentrations (allosteric effectors), the T(tense) state of hemoglobin, central cavity is larger, the R(relaxed) state of hemoglobin, central cavity is smaller, the physical form hemoglobin helix assumes when in the unbound state, the physical form hemoglobin helix assumes when in the bound state, a molecule present in high concentrations in RBC, binds to the T state of Hb, and allows for the better release of all oxygen molecules, is an allosteric effector, negatively charged, found in fetal Hb, replaces the two beta subunits, difference between the beta is that it has a serine at 143 instead of a histidine, higher affinity for oxygen than maternal Hb, a Hb mutation; a mutation from Glu6-->Val in the beta subunit decreases the solubility, causing fibrous aggregations, a Hb mutation; the loss or substantial reduction of a single Hb chain, a Hb mutation; no alpha subunits in Hb, 4 beta subunits (HbH), a Hb mutation;

enzyme stabilizes the substrate, which can lead to products, mechanisms of enzyme activity; assists in proton transfer reactions, functional groups act as acids or bases, mechanisms of enzyme activity; (30% of all enzymes) hold a substrate properly, stabilizes negative intermediates to polarize scissile bonds, participate in redox reactions, mechanisms of enzyme activity; nucleophilic groups on enzyme reacts and forms covalent bonds with substrate, usually interacts with carbonyl in serine, a bond in a substrate that is to be broken, an enzymatic process where an effector shuts down or reduces an enzymes activity; drugs and toxins exert their effects through this mechanism, enzymatic inhibition; covalent bonds permanantly change an enzyme, enzymatic inhibition; non-covalent bonding effectors stop enzymatic processes, the three general forms are competative, non-competative (pure and mixed), and uncompetative, enzymatic inhibition; where the effector resembles the substrate, binds to the active site, high [S] lessens the effect of the inhibitor, Vmax stays the same, Km is altered, enzymatic inhibition; inhibitor and substrate bind to different sites; Km stays the same, Vmax changes, enzymatic inhibition; inhibitor and substrate bind to different sites; Vmax and Km changes, enzymatic inhibition; inhibitor binds to the ES complex, Km decreases and Vmax increases, locks the substrate in position, regulatory pathways are usually controlled by these class of enzymes; in addition, the first enzyme in the pathway is usually the regulatory one and of this type, in enzymes, binding or catalytic changes cause a conformational change elsewhere, enzymatic allosterism; where the substrate and the effector molecule are identical, enzymatic allosterism; where the substrate and the effector are different, allosteric regulation; enzymes can either be found in the TT or RR state, the effector molecule shifts the enzyme to one state (hybrid TR not possible), allosteric regulation; enzymes can either be found going from TT->TR->RR, the TR hybrid is possible, cellular enzyme regulation; modification via phosphorylation of Ser, Thr, Tyr or ubiquitination of Lys, cellular enzyme regulation; some enzymes are synthesized in the inactive form, the zymogen is cleaved into the active state, this is a irreversible process, cellular enzyme regulation; enzymes that carry out the same reaction but have different kinetics, regulatory properties, forms of coenzymes, and distribution, cellular enzyme regulation; the term used to describle an enzyme formed in an inactive state that has to be cleaved in order to work.
