Abstract
<p class="first" id="d5571444e139">Phycobiliproteins (PBPs) are the main component
of light-harvesting complexes in cyanobacteria
and red algae. In addition to their important role in photosynthesis, PBPs have many
potential applications in foods, cosmetics, medical diagnosis and treatment of diseases.
However, basic researches and technological innovations are urgently needed for exploring
those potentials, such as structure and function, their biosynthesis as well as downstream
purification. For medical use and application, mechanisms underlying their therapeutic
effects must be elucidated. Focusing on these issues, this article gives a critical
review on the current status on PBPs, including their structures and functions, preparation
processes and applications. In addition, key technical challenges and possible solutions
are prospected.
