Biochemists Discover Mechanism That Helps Flu Viruses Evolve（图）
Biochemists Flu Viruses Evolve
2017/10/24
Influenza viruses mutate rapidly, which is why flu vaccines have to be redesigned every year. A new study from MIT sheds light on just how these viruses evolve so quickly, and offers a potential way t...
Evaluation of the Energetics of the Concerted Acid-Base Mechanism in Enzymatic Catalysis:The Case of Ketosteroid Isomerase
Energetics Concerted Acid-Base Mechanism Enzymatic Catalysis Ketosteroid Isomerase

Structures of enzymes invariably reveal the proximity of acidic and basic residues to reactive sites on the substrate, so it is natural and common to suggest that enzymes employ concerted mechanisms t...
The Mechanism of Triplet Energy Transfer from the Special Pair to the Carotenoid in Bacterial Reaction Centers
Triplet Energy Transfer Carotenoid Bacterial Reaction Centers
2016/5/23
The kinetics of triplet energy transfer from the primary electron donor P, a bacteriochlorophyll dimer, to the carotenoid were measured in the M182HL mutant of Rhodobacter sphaeroides photosynthetic r...

Hsp70 Protein aggregation Enzyme Polypeptide Protein function Nucleotides. The ATP hydrolysis
2014/12/11
The Hsp70 family molecular chaperones prevent protein aggregation under heat shock conditions. They are highly conserved, and have a N-terminal ATPase domain, which binds and hydrolyzes ATP, and a C-t...
