Question
Small archaeal modifier proteins, or "SAMPs," may serve the same purpose as this protein. For 10 points each:
[10h] Name this protein that can be conjugated in chains to either lysine residues or N-termini of other proteins by the E3 ligase activity of a SCF ("SKIFF") complex.
ANSWER: ubiquitin [or ubiquitination or ubiquitinylation or ubiquitylation or polyubiquitination or polyubiquitinylation or polyubiquitylation; accept ub]
[10m] The SCF-Dia2 complex poly·ubiquitin·ates Cdc6 to prevent ectopic "licensing" of this process. This process begins at "origins," or "ORIs," that are "recognized" by proteins like ORC1.
ANSWER: DNA replication
[10e] Cdc6 and ORC1 are the same protein in Archaea, indicating that they have this evolutionary relationship, contrasted with "analogous," in which two proteins share an ancestral origin.
ANSWER: homologous [or homologs or homology]
