  In conclusion, substrate enabled effective detection of L-alanylaminopeptidase activity in all Gram-negative bacteria tested here. The chromogenic substrate showed high sensitivity at a relatively low concentration (50 mgL), with no diffusion of the coloured chelate into the surrounding agar. Lack

  Introduction Proteins play an important role in cellular functions; however, being and remaining properly folded is necessary for their function. Understanding the stability of the protein is necessary to investigate the folding of proteins, as well as their conformation, functions and interactions

  2020-06-11

  

  The RING domain was previously considered sufficient to confer ubiquitination by RING-type E3 ligases. However, recent reports have shown that sequences closest to the RING domain are also important in E3 ligase function. Residues like Tyr193 in RNF4 [40], Phe296 and Arg294 in BIRC7 [31], and Lys65

  2020-06-11

  

  RING dimerization RING-type domains are found in many different structural contexts. While many exist as single-chain Proteinase K (Fig. 3A), a notable feature of RING-type E3s is their tendency to form homodimers and heterodimers (Fig. 3C–F). Homodimeric RING-type E3s include cIAP, RNF4, BIRC7

  The small intestine is the only organ responsible for the Sodium ascorbate of dietary and biliary cholesterol, leaving the unabsorbed cholesterol to be excreted in feces and together contributing to the body cholesterol homeostasis [13], [21], [33], [34]. Following intraluminal hydrolysis, free chol

  When Does Activity with Alternative Substrates Depend on Neutral Drift? In a final scenario, the alternative reaction catalyzed by an enzyme might have no significant (positive or negative) effects on the system fitness, and thus it would be invisible to natural selection and essentially subject

  Based on the SUMO–SIM interaction involved in SUMOD positioning, a SUMO2ΔSBD (SIM-binding domain; Q30A, F31A, I33A) mutant can be investigated that disrupts this important binding interface (Eisenhardt et al., 2015; Meulmeester, Kunze, Hsiao, Urlaub, & Melchior, 2008). In Fig. 4A, multiturnover assa

  Several in vivo human studies have produced conflicting results for evaluating the inhibition of OCs on the metabolism of CYP3A substrates. Balogh et al.
