Abstract

MÉTODOS E COMPOSIÇÕES PARA SILENCIAMENTO GENÉTICO APRIMORADO BASEADO EM CRISPR TIPO I-E. A interferência com base em CRISPR se tornou comum em várias aplicações a partir de circuitos genéticos para controle metabólico dinâmico. Em E. coli, o sistema CRISPR Cascade nativo pode ser utilizado para silenciar por deleção da nuclease cas3 juntamente com a expressão de arranjos de RNA guia, onde múltiplos genes podem ser silenciados a partir de um único transcrito.
