At issue is whether it is an all-trans-retinyl ester or all-trans-retinol (vitamin A). As both putative substrates interconvert rapidly in retinal pigment epithelial membranes, the choice of substrate can be ambiguous. The two enzymes that effect interconversion of all-trans-retinol and all-...
Every single repetitive sequence is referred to as a module and every module allows the enzymatic incorporation of a specific substrate into the substance synthesized by the enzyme. The products synthesized by the NRPS and PKS enzymes are often highly valuable as pharmaceuticals, such as the ...
Molecular modelling of the enzymes revealed that two of these residues, T414 and V530, are located in the active site of VvGuaS within 4 of the binding-site of the substrate, farnesyl pyrophosphate. Mutation of these two residues of VvGuaS into the corresponding polymorphisms in VvPNSeInt ...
5d). This behaviour suggests that PRC1 condensates serve as reaction crucibles, a finding that echoes those in a recent study where H2B ubiquitination enzymes were found to form a “reaction-chamber condensate,” possibly in a similar manner to PRC147. Consistent with this picture, even after ...
(Fig.2b). eDNA-derived gene clusters were predicted to encode a number of enzymes that have not previously been associated with rifamycin congener biosynthesis (e.g.,N-acyltransferases, CoA-transferases, propionyl-CoA carboxylases, methylmalonyl-CoA mutases, and lanthionine synthetase-like enzymes) ...
An enzyme or protein may be termed as thermostable if a high definite unfolding (transition) temperature (Tm) or a long half-life at a preferred high temperature is observed (Turner et al., 2007). Thermostable enzymes can be used at temperatures that enhance substrate solubility and reaction ...
Seven FA elongase isoenzymes (ELOVL1–7) with different substrate specificities are found in mammals (Kihara, 2012, 2016; Ohno et al., 2010). Disruption of Elovl1, which is responsible for the production of saturated and monounsaturated C22–C26 FAs, causes shortening of CEs and WEs, ...

bNumber of samples of each substrate in which HRÀ strains of P. syringae were detected. When fewer than 20 strains of P. syringae were isolated from the sample, all were tested for capacity to induce hypersensitivity. Otherwise, a random set of about 30 strains was tested per sample. c...
Most of the genes affected are involved in routine cell functions such as binding to calcium, RNA or protein, as well multiple enzymes and their regulators. Although these genes are needed for taste cell function, it is unlikely that they are the regulatory factors that control the processes ...
