Identifying the molecular switch that regulates autophagy in plants

Autophagy, commonly known as “self-eating,” is a cellular quality control mechanism that relieves the cell of protein aggregates and damaged organelles. This system is inert under ordinary conditions and is only activated in the presence of persistent cellular stress.

New hexameric structure of the protein triggering antibiotic resistance discovered

All living organisms require DNA replication to ensure the genetic integrity of the following generation. On the other hand, bacteria have the ability to horizontally transfer genetic information to other bacteria.

Structure of amyloid fibers formed by the protein hnRNPDL-2 determined

Using high-resolution cryo-electron microscopy (cryo-EM), UAB researchers determined the structure of amyloid fibers formed by the protein hnRNPDL-2, which has been linked to limb-girdle muscular dystrophy type 3 and concluded that the protein’s inability to form amyloid ﬁbers, rather than aggregation, would be the cause of the disease.

AI develops first-ever functional artificial protein

Scientists have developed an AI system that can produce artificial enzymes from scratch. Even though several of these enzymes’ artificially generated amino acid sequences differed noticeably from those of any known natural protein, they nonetheless performed as well in laboratory testing as those found in nature.
