A novel family of P-loop NTPases with an unusual phyletic distribution and transmembrane segments inserted within the NTPase domain
L Aravind, Lakshminarayan M Iyer, Detlef D Leipe, Eugene V Koonin Genome Biology 2004, 5:R30 (16 April 2004)
Abstract | Full text | PDF
| Cited on BioMed Central
|
Editor’s summary
