Name  ATP-dependent RNA helicase DeaD Short Name  DEAD_helicase_DeaD
Type  Family Description  RNA helicases from the DEAD-box family are found in almost all organisms andhave important roles in RNA metabolism, such as splicing, RNA transport,ribosome biogenesis, translation and RNA decay. They are enzymes that unwinddouble-stranded RNA molecules in an energy dependent fashion through thehydrolysis of NTP. DEAD-box RNA helicases belong to superfamily 2 (SF2) ofhelicases. As other SF1 and SF2 members they contain seven conserved motifswhich are characteristic of these two superfamilies [].DEAD-box is named after the amino acids of motif II or Walker B (Mg2+-bindingaspartic acid). The RNA helicase DeaD is ATP-dependent []and is induced by low temperatures []. In addition to its role in unwinding double stranded RNA, it is involved in ribosomal subunit biogenesis [].
