Lipocains: molecular model of the plasma retinol-
binding protein (PDB code:1rbp), ribbon diagram.
The retinal molecule is shown as a green CPK
model. Lipocains are proteins that transport small
hydrophobic molecules such as steroids, bilins,
retionoids and lipids. They share limited regions
of sequence similariy and a common tertiary
structure. Plasma retinol binding protein (RBP)
delivers retinol from the liver stores to the
peripheral tissues.

Plasma retinol-binding protein, mol. model

Two strands of DNA in the process of homologous
recombination forming a structure known as a
Holliday junction. This model shows the complex
formed between the E. coli RuvA protein (blue) and
RuvB (yellow) and the DNA molecule. In the DNA
molecule the different types of atoms are coloured
red, white, blue and orange.

Molecular model of G alpha (a trimeric G protein)
in complex with adenylate cyclase, alpha helices
shown as cylinders.
G alpha is shown in red with the switch regions
I and II in green. The trimeric guanine
nucleotide-binding proteins are involved as
transducers in various transmembrane signalling
systems. The G alpha (s) protein is involved in
hormonal regulation of adenylate cyclase: it
activates the cyclase in response to beta-
adrenergic stimuli.

Molecular model (no labels) of histidine phospho-
carrier protein HPR (pdb code: 1poh)(ribbon
diagram, cylinders are alpha-helices, His-15 shown
as ball-and-stick model). HPR is part of the
phosphoenolpyruvate-dependent sugar phospho-
transferase system (PTS), a major carbohydrate
active transport system moving certain hexoses
across the cytoplasmic membrane of bacteria and
mycoplasmas. His-15 at active site of HPR accepts
a multi-enzyme system (Enzyme I) and transfers it
to various sugar-specific PTS permeases.
