    Image_4_Substrate Specificity of Acyltransferase Domains for Efficient Transfer of Acyl Groups.TIF by Jie-Jie Shen (5600129)

    Published 2018
    “…In Streptomycestsukubaensis YN06, we found that AT4<sub>FkbB</sub> [an AT in the fourth module of tacrolimus (FK506) PKS] transferred both allylmalonyl (allmal) and emthylmalonyl (ethmal) units to ACPs, which was supposed responsible for the production of both FK506 and its analog FK520, respectively. Mutations of five residues in AT4<sub>FkbB</sub> (Q119A, L185I-V186D-V187T, and F203L) caused decreased efficiency of allmal transfer, but a higher ratio of ethmal transfer, supposedly due to less nucleophilic attacks between Ser599 in the active site of AT4<sub>FkbB</sub> and the carbonyl carbon in the allmal unit, as observed from molecular dynamics simulations. …”

    Evaporation of Dilute Sodium Dodecyl Sulfate Droplets on a Hydrophobic Substrate by Wojciech Kwieciński (7037669)

    Published 2019
    “…In contrast to the constant contact angle of an evaporating sessile water droplet, we observed that, at the same surface, the contact angle of an SDS laden droplet with concentration below 0.5 CMC first decreases, then increases, and finally decreases, resulting in a local contact angle minimum. …”
