O QUE SIGNIFICA RIBOZYME EM INGLÊS
Ribozyme
Uma ribozima é uma molécula de ARN que é capaz de catalisar reações bioquímicas específicas, semelhante à ação das enzimas protéicas. A descoberta de ribozimas de 1982 demonstrou que o RNA pode ser tanto material genético quanto um catalisador biológico, e contribuiu para a hipótese mundial do ARN, o que sugere que o RNA pode ter sido importante na evolução dos sistemas pré-bióticos auto-replicantes. Também denominado ARN catalítico, as ribozimas funcionam dentro do ribossoma para vincular os aminoácidos durante a síntese protéica, e em uma variedade de reações processuais de ARN, incluindo o splicing de ARN, replicação viral e transferência de biossíntese de RNA. Exemplos de ribozimas incluem a ribozima de cabeça de martelo, a ribozima VS e a ribozima de cabelo. Pesquisadores que estudam a origem da vida produziram ribozimas no laboratório que são capazes de catalisar sua própria síntese em condições muito específicas, como uma ribozima de ARN polimerase. A mutagênese e a seleção foram realizadas, resultando em isolamento de variantes melhoradas da ribozima de polimerase "Round-18" de 2001. "B6.
definição de ribozyme no dicionário inglês
A definição de ribozima no dicionário é uma molécula de ARN capaz de catalisar uma reação química, geralmente a clivagem de outra molécula de RNA.
