We constructed a standardized protein folding kinetics database (PFDB) in which the logarithmic rate constants of all listed proteins are calculated at the standard temperature (25 °C). A temperature correction based on the Eyring-Kramers equation was introduced for proteins whose folding kinetics were originally measured at temperatures other than 25 °C. We verified the temperature correction by comparing the logarithmic rate constants predicted and experimentally observed at 25 °C for 14 different proteins, and the results demonstrated improvement of the quality of the database. PFDB consists of 141 (89 two-state and 52 non-two-state) single-domain globular proteins, which has the largest number among the currently available databases of protein folding kinetics. PFDB is thus intended to be used as a standard for developing and testing future predictive and theoretical studies of protein folding. PFDB can be accessed from the following link: http://lee.kias.re.kr/~bala/PFDB .

Steered Molecular Dynamics (SMD) simulation is a powerful computational simulation technique that enables the controlled manipulation of molecular systems by applying external forces. This method is frequently utilized to investigate the slow processes of biomolecular systems that occur within sub-second to second time scales, achieved through SMD simulations that only span nanoseconds. SMD simulation can be utilized to study the detailed mechanism of protein conformational changes, protein unfolding, and ligand dissociation, etc.

Understanding how proteins discriminate between preferred and non-preferred ligands ('selectivity') is essential for predicting biological function and a central goal of protein engineering efforts, yet the biophysical mechanisms underpinning selectivity remain poorly understood. Towards this end, we study how variants of the promiscuous transcription factor (TF) MAX (H. sapiens) alter DNA specificity and selectivity, yielding >1700 Ks and >500 rate constants in complex with multiple DNA sequences.

Molecular chaperones are essential throughout a protein's life and act already during protein synthesis. Bacteria and chloroplasts of plant cells share the ribosome-associated chaperone trigger factor (Tig1 in plastids), facilitating maturation of emerging nascent polypeptides. While typical trigger factor chaperones employ three domains for their task, the here described truncated form, Tig2, contains just the ribosome binding domain.

Background: The balance of redox states is crucial for maintaining physiological homeostasis. For decades, the focus has been mainly on the concept of oxidative stress, which is involved in the mechanism of almost all diseases. However, robust evidence has highlighted that reductive stress, the other side of the redox spectrum, plays a pivotal role in the development of various diseases, particularly those related to metabolism and cardiovascular health.

Aggregation of alpha-synuclein (αsyn) plays an integral role in Parkinson's disease (PD) and Dementia with Lewy bodies (DLB). 14-3-3θ is a highly expressed brain protein with chaperone-like activity that regulates αsyn folding. 14-3-3θ overexpression reduces αsyn aggregation, transmission between cells, and neuronal loss, while 14-3-3 inhibition promotes αsyn pathology.
