Typically, proteins do not act in isolation, but rather perform their functions cooperatively within a network of functionally related proteins.
It should be noted that despite the diversity of the criteria by which protein domains are defined, their common property is the ability to perform their functions, which are realized by the functional protein sites.
Proteins interact with other proteins or biomolecules to perform their functions, and protein complexes are the fundamental functional units of these macromolecular systems.
In the case of Biddle's T, the team members had to perform their functions in perfect synchrony.
Indeed, the company's privacy policy, posted on its Web site, advises clients that subcontractors "may have access to your personal information as necessary to perform their functions".
The incident, he says, raises questions about how much information government agencies need to keep — and how long they need to keep it — to perform their functions.
"For those in command and control of particular policing activities, and for those in charge of a police investigation into the death of a person in police custody, to perform their functions differently by reference to the race of the people they are dealing with is also, in my respectful opinion, an affront to the rule of law," Mortimer wrote.
Transcription factors must often be chemically modified to perform their functions.
In particular, FRET investigations have shown that biomolecules adopt different conformational structures to perform their functions.
Moreover, no external control or the power source is needed for them to be able to perform their functions.
Diverse home appliances, such as refrigerators, cooling & heating devices, boilers, TVs, and lighting apparatus, perform their functions for user convenience.
