Abstract This paper investigates a feature tracking control method for visual servoing (VS) manipulators adaptive dynamic programming (ADP)-based the unknown dynamics. The major superiority of ADP-based optimal lies in that problem is converted to error with cost function. Moreover, an neural network observer developed approximate entire uncertainties, which are utilized construct improved By e...

The role played by ADP in modulating cross-bridge function has been difficult to study, because it is hard to buffer ADP concentration in skinned muscle preparations. To solve this, we used an analog of ADP, spin-labeled ADP (SL-ADP). SL-ADP binds tightly to myosin but is a very poor substrate for creatine kinase or pyruvate kinase. Thus ATP can be regenerated, allowing well-defined concentrati...

Pseudomonas aeruginosa produces two ADP-ribosyltransferases, exotoxin A and exoenzyme S (ExoS). Although the physiological target protein remains to be defined, ExoS has been shown to ADP-ribosylate several eukaryotic proteins in vitro, including vimentin and members of the family of low-molecular-weight GTP-binding proteins. Recently, ExoS ADP-ribosyltransferase activity has been detected in t...

ATP/ADP translocases are a hallmark of obligate intracellular pathogens related to chlamydiae and rickettsiae. These proteins catalyze the highly specific exchange of bacterial ADP against host ATP and thus allow bacteria to exploit their hosts' energy pool, a process also referred to as energy parasitism. The genome sequence of the obligate intracellular pathogen Lawsonia intracellularis (Delt...

Recently, we used an ADP recycling approach to examine mouse skeletal muscle (SkM) mitochondrial function over respiratory states intermittent between state 3 and 4. We showed that respiration energized at complex II by succinate, in the presence of rotenone to block complex I, progressively increased with incremental additions of ADP. However, in the absence of rotenone, respiration peaked at ...

Analysis of poly(ADP-ribose) synthesized in cellular lysates or in isolated nuclei on 100-cm-long thin gels of 20% polyacrylamide, 2.5 M urea permits determination of the exact size of poly(ADP-ribose) molecules using labeled oligonucleotides as molecular weight markers. The size and concentration of poly(ADP-ribose) molecules increase at time intervals during its synthesis. Differences in the ...

ADP-ribose-based intermediates, including PARP-generated monoand poly(ADP-ribose) post-translational modifications, are important to a number of cellular signalling processes. The reversal of poly(ADP-ribosyl)ation is mostly attributed to PARG, which however cannot remove the final protein-linked mono(ADP-ribose) residue. Three recent studies, one of them in The EMBO Journal, now report that ce...

Myosin is thought to generate movement of actin filaments via a conformational change between its light-chain domain and its catalytic domain that is driven by the binding of nucleotides and actin. To monitor this change, we have measured distances between a gizzard regulatory light chain (Cys 108) and the active site (near or at Trp 130) of skeletal myosin subfragment 1 (S1) by using luminesce...

Antibody-dependent phagocytosis (ADP) is a potentially important immune mechanism to clear HIV. How HIV-specific ADP responses mature during HIV infection or in response to vaccinations administered, including the partially successful RV144 HIV vaccine, is not known. We established a modified ADP assay to measure internalisation of HIV antibody (Ab)-opsonised targets using a specific hybridisat...

Erythrocytes from cancer patients exhibited up to fivefold higher NAD glycohydrolase activities than control erythrocytes from normal subjects and also similarly increased [14C] ADP-ribose uptake values. When [adenosine-14C] NAD was used instead of free [14C] ADP-ribose, the uptake was dependent on ecto-NAD glycohydrolase activity. This was reflected in the inhibition of ADP-ribose uptake from ...
