1 активный центр фермента
часть молекулы фермента, ответственная за специфическое присоединение и превращение субстрата. Образуется функциональными группами аминокислотных остатков, расположенными строго определенным образом в пространстве за счет сближения отдельных участков полипептидной цепи. Структура А.ц.ф. соответствует (комплементарна) химическому строению субстрата, благодаря чему достигается специфичность действия фермента. Часто в построении А.ц.ф. участвуют коферменты или атомы металлов. В одной молекуле фермента может быть несколько А.ц.ф.Толковый биотехнологический словарь.

2 способность
Способность (работать на нескольких топливах)-- A small gas turbine has potential advantage, including multi-fuel ability, light weight and portability, reliability, and excellent cold weather starting. Способность - ability, capability, capacity, power (в положительном смысле); potential (часто в отрицательном смысле)Photosynthetic bacteria generate oxidizing power by photolysis of water. (... приобретают окислительную способность...)The content of heavy metal is also important due to the potential to catalyze soot formation.Способность к (ингибированию)-- The inhibiting capacity is greatly dependent on the degree of specificity for the active center. Способность кThe phenomenon of embrittlement of steel subject to high temperatures was recognized along with the potential of notches in accelerating this embrittlement.Extracellular conditions influence the capacities for enzyme synthesis.Русско-английский научно-технический словарь переводчика > способность
