Examples

  • In a breakthrough discovery, we found that the target substrate is covalently modified by multiple moieties of APF-1, a reversible modification that renders the protein substrate susceptible to degradation.

  • When a language, Latin in this case, imposes on a preexisting one, as Latin did Celtic, the original local language is called a substrate language: it sits on a stratum under sub the new language.

  • Typically, the light in the substrate is internally reflected and runs parallel and not perpendicular.

  • To overcome this problem, the Purdue researchers developed a means to create LEDs on low-cost, metal-coated silicon wafers, whereby the the silicon substrate is metalized with a built-in reflective layer of zirconium nitride.

  • Techniques for creating easel paintings will not successfully color cloth for clothing even if the common substrate is a textile, but neither will they necessarily provide good color for a wall or a metal sign. reference The preparation of the substrate, the application of a coloring material (or materials) and how it is made permanent, the tools needed for application — all of these varied.

  • Accordingly, we hypothesized that covalent attachment of multiple moieties of APF-1 to the target substrate is necessary to render it susceptible to degradation by a downstream protease that recognizes only tagged but not untagged proteins, followed by the release of free and reusable APF-1.

  • Added labeled reaction product rebounds to substrate when unlabeled substrate is added showing that the product form of the enzyme is slow to recycle, the Britton counterflow effect36, 37.

    Irwin Rose - Autobiography

  • Changes in the active site of an enzyme that occur when a substrate is converted to product must be reversed before the reaction can occur again.

    Irwin Rose - Autobiography

  • If, as Hameroff-Penrose suggests, the causal substrate is quantum-dynamic on the seriously sub-cellular level of NCCs, cognitive science will have to accept global properties that don't magically 'emerge', but are there all the way down – it's called "Coherence," the technical term for quantum entanglement (non-locality).
