Transfer functions

Stabilizing the depth of the Towed Underwater Vehicle (TUV) under the impact of ocean waves is the first problem when building a control and monitoring system for TUV. Many strategies and control methods have been proposed in different studies, but they are not a general standard.

In this review, we summarize recent progress in studying three main classes of prenyltransferases: (a) isoprenyl pyrophosphate synthases (IPPSs), which catalyze chain elongation of allylic pyrophosphate substrates via consecutive condensation reactions with isopentenyl pyrophosphate (IPP) to generate linear polymers with defined chain lengths; (b) protein prenyltransferases, which catalyze the transfer of an isoprenyl pyrophosphate (e.g. farnesyl pyrophosphate) to a protein or a peptide; (c) prenyltransferases, which catalyze the cyclization of isoprenyl pyrophosphates.

4-Coumarate:CoA ligase (4CL) is involved in the formation of coenzyme A thioesters of hydroxycinnamic acids that are central substrates for subsequent condensation, reduction, and transfer reactions in the biosynthesis of plant phenylpropanoids. Previous studies of 4CL appear to suggest that many isoenzymes are functionally equivalent in supplying substrates to various subsequent branches of phenylpropanoid biosyntheses. In contrast, divergent members of a 4CL gene family were identified in soybean (Glycine max L.).

The functional replacement of the primary ubiquinone (QA) in the photosynthetic reaction center (RC) from Rhodo-bacter sphaeroideswith synthetic vitamin K derivatives has provided a powerful tool to investigate the electron transfer mechanism. To investigate the binding mode of these qui-nones to theQAbinding sitewe have determined the binding free energy and charge recombination rate from QA ± to D + (kAD) of 29 different 1,4-naphthoquinone derivatives with systematically altered structures.

Multimolecular complexes involving the eukaryotic elongation factor 1A (eEF1A) have been suggested to play an important role in the channeling (vectorial transfer) of tRNAduring protein synthesis [Negrutskii, B.S.&El’skaya, A.V. (1998)Prog. Nucleic Acids Res. Mol. Biol.60,47–78]. Recently we have demonstrated that besides performing its canonical function of forming a ternary complex with GTP and aminoacyl-tRNA, the mammalian eEF1A can produce a noncanonical ternary complex with GDP and uncharged tRNA [Petrushenko, Z.M., Negrutskii, B.S.,...

Mammalian adenylate cyclases are predicted to possess complex topologies, comprising two cassettes of six trans-membrane-spanningmotifs followedbyacytosolic, catalytic ATP-binding domain. Recent studies have begun to provide insights on the tertiary assembly of these proteins; crystal-lographic analysis has revealed that the two cytosolic domains dimerize to forma catalytic core, whilemore recent biochemical and cell biological analysis shows that the two transmembrane cassettes also associate to facilitate the functional assembly and trackingof the enzyme. ...

ATP-regenerating enzymes may have an important role in maintaining ATP levels in mitochondria-like kinetoplast organelle and glycosomes in parasitic protozoa. Adenylate kinase (AK) (ATP:AMP phosphotransferase) catalyses the reversible transfer of thec-phosphate group from ATP to AMP, releasing twomolecules ofADP. This study describes cloningand functional characterizationof the gene encoding AK2fromagenomic libraryofLeishmaniadonovaniandalso its expression in leishmania promastigote cultures.

Cryptochromes are blue-light photoreceptors sharing sequence similarity to photolyases, a class of flavoenzymes catalyzing repair ofUV-damagedDNAvia electron transfer mechanisms. Despite significant amino acid sequence simi-larity in both catalytic and cofactor-binding domains, cryptochromes lack DNA repair functions associated with photolyases, and the molecular mechanism involved in cryptochrome signaling remains obscure.

This paper reports the isolation and characterization of the regulatory moiety of the multicomponent enzyme phenol hydroxylase fromAcinetobacter radioresistensS13 grown on phenol as the only carbon and energy source. The whole enzyme comprises an oxygenase moiety (PHO), a reductase moiety (PHR) and a regulatory moiety (PHI). PHR contains one FAD and one iron-sulfur cluster, whose function is electron transfer from NADH to the dinuclear iron centre of the oxygenase.

The opportunity to design enzymatic systems is becoming more feasible due to detailed knowledge of the structure of many proteins. As a first step, investigations have aimed to redesign already existing systems, so that they can performa function different from the one for which they were syn-thesized. We have investigated the interaction of electron transfer proteins fromdifferent systems inorder to check the possibility of heterologous reconstitution among members of different chains.

A wide range of approaches has been applied to examine the quaternary structure of G protein-coupled receptors, the basis of such protein–protein interactions and how such interactions might modulate the pharmacology and function of these receptors. These include coimmunoprecipitation, var-ious adaptations of resonance energy transfer techniques, functional com-plementation studies and the analysis of ligand-binding data.
