Some oncogenes can also stimulate the transcription of proteins that bind to MDM2 and inhibit its activity.

Some antibacterial drugs such as penicillin interfere with the production of peptidoglycan by binding to bacterial enzymes known as penicillin-binding proteins or transpeptidases.

Some such proteins are highly specific in their function, such as protein disulfide isomerase ; others are very general and can be of assistance to most globular proteins-the prokaryotic GroEL / GroES system and the homologous eukaryotic Heat shock proteins Hsp60 / Hsp10 system fall into this category.

Some proteins explicitly take advantage of the fact that they can become kinetically trapped in a relatively high-energy conformation due to folding kinetics.

# Some proteins involved in cell adhesion prevent tumor cells from dispersing, block loss of contact inhibition, and inhibit metastasis.

Some people define narcotics as substances that bind at opioid receptors ( cellular membrane proteins activated by substances like heroin or morphine ) while others refer to any illicit substance as a narcotic.

Some poisons are also toxins, usually referring to naturally produced substances, such as the bacterial proteins that cause tetanus and botulism.

Some proteins never fold in cells at all except with the assistance of chaperone molecules, which either isolate individual proteins so that their folding is not interrupted by interactions with other proteins or help to unfold misfolded proteins, giving them a second chance to refold properly.

Some of us might be inclined to argue, in fact, that an independence of mind and action and an intolerance of regimentation, either mental or physical, are particularly Southern traits.

Some years ago Julian Huxley proposed to an audience made up of members of the British Association for the Advancement of Science that `` man's supernormal or extra-sensory faculties are ( now ) in the same case as were his mathematical faculties during the ice age ''.

Some are fishing, some driving the team, and many are sitting indolently on the banks of the river.

Some historians have found his point of view not to their taste, others have complained that he makes the Tory tradition appear `` contemptible rather than intelligible '', while a sympathetic critic has remarked that the `` intricate interplay of social dynamics and political activity of which, at times, politicians are the ignorant marionettes is not a field for the exercise of his talents ''.

Some of the marble busts in the park are of young Englishmen who fought and died for Garibaldi.
