((( Latest Protein Spotlight issue: the colour red ))) March 2024 ------------------------------------------------------------------------ Plants cannot walk. Unable to drift down to the local café, attend this evening's book launch or gate-crash a party, flowers have had to resort to other ways of connecting. True, their roots may wander and branches may wave, but really what appears above ground level is pretty moored. Yet that is where their reproductive organs are, which need to meet so that the plant's pollen can be fertilized. This is achieved indirectly by using animal pollinators - whose attention, however, needs to be grabbed. Nectar fulfils this role wonderfully. A sweet liquid secreted by flowers, nectar is concocted to tempt insects or vertebrates whose bodies, as they feed off it, may inadvertently pick up pollen in one flower and deposit it, in all innocence, on another flower's stigma. So as not to be missed, a little like waving a flag, a flower's nectar may occasionally be brightly coloured: yellow, deep purple, blue, green, red or even black. In this light, the striking red nectar of Nesocodon mauritianus, a blue flower endemic to the island of Mauritius, seems to have evolved to attract a day gecko and is synthesized thanks to the close collaboration of three enzymes: Nec1, Nec2 and Nec3.

Latest Protein Spotlight issue: seizure

((( Latest Protein Spotlight issue: seizure ))) March 2024 ------------------------------------------------------------------------ Many years ago, I was sitting opposite a man whose body suddenly froze. His eyes seemed to be staring at something on the wall behind me while his left hand drew small circles in the air, repetitively. I had no idea what was happening to him until he came back to his senses and told me that he had just had an epileptic fit. Deeply embarrassed, he got up and left the room. Many of us will have witnessed a close relative, a friend, an acquaintance or perhaps simply a passerby, under the influence of an epileptic seizure - which are frequently more violent and alarming than the one I experienced that day. Epilepsy affects millions of people worldwide. However, what is happening on the molecular scale remains elusive. What we do know is that an epileptic fit is caused by neural activity that has suddenly gone out of control. In this light, researchers discovered two tarantula venom peptides - Aa1a and Ap1a - which inhibit channels that are used to relay signals in our central nervous system. Peptides such as these could perhaps be used to keep abnormal neural activity at bay in people suffering from epilepsy.
