The creation of a web bubble, or link farm, is a technique used by web spammers to increase the visibility of a target page T. Specialized mobile agents, called Web Marshals, are employed to detect and dismantle link farms. As the number of Web Marshals, as well as the number of hops needed to disassemble a link farm, need to be minimized, this kind of process can be seen as a graph decontamina...

Neisseria gonorrhoeae isolated from patients with disseminated infection (DGI) often resist complement (C')-dependent killing by normal human serum (NHS) and less commonly by convalescent DGI serum. 7 of 10 NHS specimens completely inhibited killing of serum-resistant (ser(r)) gonococci by convalescent or immune DGI serum. Immunoglobulin G (IgG) purified from NHS was shown to be the blocking ag...

The C-terminal domain (CTD) of the largest RNA polymerase II (RNAPII) subunit undergoes dynamic phosphorylation to support transcription-associated events and drive the transcription cycle. In mammalian cells, it comprises 52 repeats of the heptapeptide sequence Tyr(1)–Ser(2)–Pro(3)–Thr(4)–Ser(5)–Pro(6)–Ser(7). While important functions for Ser(2)-, Ser(5)-, and Ser(7)-phosphorylation have prev...

In different phases of the transcription cycle, RNA polymerase (Pol) II recruits various factors via its C-terminal domain (CTD), which consists of conserved heptapeptide repeats with the sequence Tyr(1)-Ser(2)-Pro(3)-Thr(4)-Ser(5)-Pro(6)-Ser(7). We show that the CTD of transcribing yeast Pol II is phosphorylated at Tyr(1), in addition to Ser(2), Thr(4), Ser(5), and Ser(7). Tyr(1) phosphorylati...
