Creative Biostructure has accumulated a wealth of experience in studying the structures and functions of transporters. Creative Biostructure experts provide MemPro™ services for the construction, expression, purification, crystallization, data collection and structure determination of the transporters with further drug design and functional analysis.
About one-third of the membrane
proteins are transporters. Ubiquitous membrane phenomena in
bacteria and vertebrates are essentially the same, and it includes membrane
biogenesis, lipid biosynthesis, protein insertion, fluidity determination and
molecular transport. Understanding of their functions depends on the structural
information, biosynthetic rules governing the overall biogenesis, folding and
assembly as well as the principles behind the transient interactions between ‘soluble’
or in-transit proteins with membranes of different lipid compositions.
Transporters (carrier proteins)
Membrane transports play crucial roles in
all biological processes: e.g.,
nutrient uptakes, drug and toxin efflux, establishment of electrochemical
gradients, metabolite excretion and intercellular communication. All these activities
are dependent on lipid–protein interactions. However, such effectiveness can turn
out to be harmful: an example is seen in the emergence of multi-drug resistant
pathogenic microbe strains caused by the excessive use of antibiotics in
medicine and the meat processing industry. Therefore,
it is very important to understand the nature of the lipid-dependent

Transporters associated with various
multi-drug resistant pathogens and diseases could be studied computationally
and specifically targeted during drug design. The simple fact that 10% of a
proteome could be transport proteins suggests their important functions. The
current opinion believes these proteins exist only in a membrane-integrated
state. Limited evidence, however, suggests that these proteins can exist in properly
folded and near-native ‘soluble’ states, whose properties are still being
studied by structural biology approaches.
has drawn increasing attention on studying their functions and structures since
