 15 termes

lac promoter  n.

p. 326

As you now know, RNAP needs stimulation by cAMP-CRP. Once bound by cAMP, CRP binds to sequences upstream of the lac promoter and interacts with RNAP to help it clear the promoter, allowing the operon to be transcribed.
last universal common ancestor  n. (LUCA)

p. 12

The two prokaryotic groups, Bacteria and Archaea, branched early on from a common ancestor, and from them all other life forms originated. Just how this last universal common ancestor, or LUCA, originated is anybody's guess (Box 1,2).
LAT  n. (latency-associated transcript)

p. 703

Consequently, only one HSV gene is highly expressed, that producing the latency-associated transcript (LAT).
latency-associated transcript  n. (LAT)

p. 703

Consequently, only one HSV gene is highly expressed, that producing the latency-associated transcript (LAT).
latent virus  n.

p. 493

Latent viruses cause infections that are often characterized by symtomatic bouts appearing long after the virus is acquired.
Laxus oneistus  [nom científic]

p. 106

Some marine nematodes, such as the worm Laxus oneistus, secrete a mucus around their body to attract and bind specific rod-shaped bacteria (Fig. 4.20).
leukocidin  n.

p. 659

An even more aggressive virulence strategy is to kill neutrophils outright, and the staphylococcal Panton-Valentine leukocidin (PVL) does just that.
lipid micelle  n.

p. 32

A critical event in the formation of the first protocells must have involved the engulfment of self-replicating and catalytic biological molecules, most likely RNAs, by lipid micelles.
listeriolysin O  n.

p. 677

In the next section we'll learn about a few of them -the toxin listeriolysin O, phospholipases, and an actin-recruiting protein ActA.
Lokiarchaeota  [nom científic]

p. 411

One of the candidate phyla, the "Lokiarchaeota", is particularly puzzling because its members are phylogenetically closer to eukaryotes than to prokaryotes and their genomes possess many eukaryotic-like genes.
LPS core  n.

p. 40

As the name indicates, LPS is a lipid modified with sugar: it consists of one glycolipid (lipid A) and one or two sugar portions (LPS core and O antigen).
LUCA  n. (last universal common ancestor)

p. 12

The two prokaryotic groups, Bacteria and Archaea, branched early on from a common ancestor, and from them all other life forms originated. Just how this last universal common ancestor, or LUCA, originated is anybody's guess (Box 1,2).
LuxI-LuxR system  n.

p. 355

The LuxI-LuxR system. [...] An enzym (LuxI) makes a signal or autoinducer and a response regulator (LuxR) that binds the signal.
lysogenic virus  n.

p. 464

This phage is a temperate or lysogenic virus. It maintains the full infective potential but "hitched a ride" on the cell's chromosome before going on attack mode.
lytic virus  n.

p. 464

Such an infective cycle that leads to the generation of the viral progeny and death of the host cell is typical of lytic viruses.
