The Nucleus Flashcards
(26 cards)
H-NS
Histone-like nucleoid structuring protein; abundant nucleoid-associated protein
HUα, HUβ
Abundant nucleoid-associated protein
IHF
Integration host factor; abundant nucleoid-association protein
Gyrase
DNA supercoiling
Topoisomerase IV
DNA supercoiling; possible role in decatenation (removing interlinks between sister chromosomes)
Topoisomerase I
DNA supercoiling
MukB
Chromosome condensation
MukE
Chromosome condensation
MukF
Chromosome condensation
RNA polymerase
Transcribing RNA polymerase may be a major source of restraints on DNA structure
spoIIIE
moves the new copy of the chromosome to one end of the cell so that it ends up in the spore
oriC
The origin of replication (part that winds up in the new spore)
terC
terminator of replication (part that stays in original cell)
SMC proteins
structural maintenance of chromosomes
Chromosome domains
The region where each particular chromosome resides in the nucleus.
Interchromosomal domains
Area between chromosomes
Nucleolus
Site for rRNA production
Ribosomal RNA
Speckles
Contain all the RNA splicing enzymes

NLS
Nuclear localization signals
Karyopherin family of proteins
NES
Nuclear export proteins
Crm1
Most common exportin protein
