Atypical homodimerization revealed by the structure of the (S)‐enantioselective haloalkane dehalogenase DmmarA from Mycobacterium marinum

Acta Crystallographica Section D, Volume 79, Issue 11, Page 956-970, November 2023., 2023
Crystallographic structures of the (S)‐enantioselective haloalkane dehalogenase DmmarA from the waterborne pathogenic microbe Mycobacterium marinum were determined at 1.6 and 1.85 Å resolution. The structures reveal a previously unobserved mode of homodimerization, which is predominantly mediated through unusual L5‐to‐L5 loop interactions.Haloalkane ...

Increasing the bulk of the 1TEL–target linker and retaining the 10×His tag in a 1TEL–CMG2‐vWa construct improves crystal order and diffraction limits

Acta Crystallographica Section D, Volume 79, Issue 10, Page 925-943, October 2023., 2023
Using a 1TEL–CMG2‐vWa construct, evidence is provided to support limiting the flexibility of linkers between TELSAM and proteins of interest and considering retaining polyhistidine purification tags in TELSAM‐fusion constructs. The phenomenon of TELSAM‐polymer flipping is also identified and a correction strategy is developed.TELSAM‐fusion ...

A temperature‐compensated linear GaAs HBT power amplifier for small‐cell applications in −25 to 125∘C$^\circ \rm C$ lunar environment

Electronics Letters, Volume 58, Issue 18, Page 684-686, August 2022., 2022
Abstract A two‐stage 920–960 MHz power amplifier (PA) in GaAs heterojunction bipolar transistor (HBT) process is demonstrated for small‐cell communications in the lunar environment. To cope with the temperature fluctuations during lunar days, a novel complementary to absolute temperature (CTAT) biasing scheme is proposed for the PA to achieve an ultra ...
