Holocarboxylase synthetase (HCS, human) and BirA (Escherichia coli) are biotin protein ligases that catalyze the ATP-dependent attachment of biotin to apocarboxylases. Biotin attachment occurs on a highly conserved lysine residue within a consensus sequence (Ala/Val-Met-Lys-Met) that is found in carboxylases in most organisms. Numerous studies have indicated that HCS and BirA, as well as biotin protein ligases from other organisms, can attach biotin to apocarboxylases from different organisms, indicating that the mechanism of biotin attachment is well conserved. In this study, we examined the cross-reactivity of biotin attachment between human and bacterial biotin ligases by comparing biotinylation of p-67 and BCCP87, the biotin-attachment domain fragments from human propionyl-CoA carboxylase and E. coli acetyl-CoA carboxylase, respectively. While BirA has similar biotinylation activity toward the two substrates, HCS has reduced activity toward bacterial BCCP87 relative to its native substrate, p-67.
Biotin protein ligase of is the 35. or that the presence of the reaction intermediate impedes access of subtilisin to the cleavage site. The disordered loop containing residues 115C123 lies close to the biotin binding site, and residues 115C118 become ordered in the crystal structure when biotinyl-lysine occupies the active site. Because of the similarity to nucleotide-binding sequences in protein buy 118876-58-7 kinases, the sequence 115GRGRRG120 within this loop had been thought to function in ATP binding (Buoncristiani et al. 1986; Wilson et al. 1992). However, a recent mutational analysis shows that this sequence has a role in biotin binding (Kwon and Beckett 2000). No function has been identified previously for the C-terminal domain comprising residues 274C321, which shows structural similarity to the Src homology 3 domains (Noble et al. 1993). However, recent evidence of safety by biotinyl-5-AMP buy 118876-58-7 against hydroxyl radical cleavage from the BirA backbone at a number of sites ...

N2 - There is a well documented need to replenish the antibiotic pipeline with new agents to combat the rise of drug resistant bacteria. One strategy to combat resistance is to discover new chemical classes immune to current resistance mechanisms that inhibit essential metabolic enzymes. Many of the obvious drug targets that have no homologous isozyme in the human host have now been investigated. Bacterial drug targets that have a closely related human homologue represent a new frontier in antibiotic discovery. However, to ...

Extension of the phosphorous moiety by a methylene spacer resulted in weaker inhibition at high ATP levels suggesting that the phosphorous group was overlapping with the 7 -phosphate of ATP rather than the carbamate carboxyt site. This was confirmed by the crystal structure of 7-( 1-hydroxyethyl)-9-phosphonononanoic acid (KU843) complexed with the enzyme. In general, phosphorous-containing inhibitors that were dianionic showed weaker inhibition ...

During mid‐oogenesis, a massive supply of nucleotides is required for the synthesis of cellular DNA and RNA. Nurse cells in egg chambers of stages 2-10 undergo 10-12 cycles of endoreplication of nuclear DNA [21] producing an approximately 1,000‐fold increase in their DNA content. Endoreplication is essential to support increased transcription and protein production for deposition into developing oocytes [22]. Likewise, RNA production, particularly ribosomal RNA, is strikingly upregulated in nurse cells from these same stages in parallel with increases in ribosomal gene copy number [23]. The presence of CTPS filaments in Drosophila ovarian germ cells at stages with a high demand for CTP, together with the observation that reduced CTPS expression is associated with defects in oogenesis, suggests that CTPS filaments are assembled to promote CTP biosynthesis and support endoreplication. Consistent with this model, the diameters of DAck86 nurse cell nuclei were significantly smaller than ...

Eukaryotic complex phototrophs exhibit a colorful evolutionary history. At least three independent endosymbiotic events accompanied by the gene transfer from the endosymbiont to host assembled a complex genomic mosaic. Resulting patchwork may give rise to unique metabolic capabilities; on the other hand, it can also blur the reconstruction of phylogenetic relationships. The ornithine-urea cycle (OUC) belongs to the cornerstone of the metabolism of metazoans and, as found recently, also photosynthetic stramenopiles. We have analyzed the distribution and phylogenetic positions of genes encoding enzymes of the urea synthesis pathway in eukaryotes. We show here that metazoan and stramenopile OUC enzymes share common origins and that enzymes of the OUC found in primary algae (including plants) display different origins. The impact of this fact on the evolution of stramenopiles is discussed here.. ...

A deficiency in HCS results in biotin-responsive multiple carboxylase deficiency (MCD). We have identified six different point mutations in the HCS gene in nine patients with MCD. Two of the mutations are frequent among the MCD patients analyzed. Four of the mutations cluster in the putative biotin-binding domain as deduced from the corresponding Escherichia coli enzyme and consistent with an explanation for biotin-responsiveness based on altered affinity for biotin. The two others may define ...
As the spread of antibiotic resistant bacteria steadily increases, there is an urgent need for new antibacterial agents. Because fatty acid synthesis is only used for membrane biogenesis in bacteria, the enzymes in this pathway are attractive targets for antibacterial agent development. Acetyl-CoA carboxylase catalyzes the committed and regulated step in fatty acid synthesis. In bacteria, the enzyme is composed of three distinct protein components: biotin carboxylase, biotin carboxyl carrier protein, and carboxyltransferase. Fragment-based screening revealed that amino-oxazole inhibits biotin carboxylase activity and also exhibits antibacterial activity against Gram-negative organisms. In this report, we redesigned previously identified lead inhibitors to expand the spectrum of bacteria sensitive to the amino-oxazole derivatives by including Gram-positive species. Using 9,411 small organic building blocks, we constructed a diverse combinatorial library of 1.2 × 108 amino-oxazole derivatives. A subset
Approach and Results-Using both rat balloon injury and mouse wire injury models, we identified CTP synthase 1 (CTPS1) as one of the potential targets that may be used for developing therapeutics for treating neointima-related disorders. CTPS1 was induced in proliferative SMCs in vitro and neointima SMCs in vivo. Blockade of CTPS1 expression by small hairpin RNA or activity by cyclopentenyl cytosine suppressed SMC proliferation and neointima formation. Surprisingly, cyclopentenyl cytosine had much less effect on EC proliferation. Of importance, blockade of CTPS1 in vivo sustained the re-endothelialization as a result of induction of CTP synthesis salvage pathway enzymes nucleoside-diphosphate kinase A and B in ECs. Diphosphate kinase B seemed to preserve EC proliferation via use of extracellular cytidine to synthesize CTP. Indeed, blockade of both CTPS1 and diphosphate kinase B suppressed EC proliferation in vitro and the re-endothelialization in vivo.. ...
Vaccinia virus thymidylate kinase, although similar in sequence to human TMP kinase, has broader substrate specificity and phosphorylates (E)-5-(2-bromovinyl)-dUMP and dGMP. Modified guanines such as glyoxal-dG, 8-oxo-dG, O(6)-methyl-dG, N(2)-ethyl-dG and N(7)-methyl-dG were found present in cancer cell DNA. Alkylated and oxidized dGMP analogs were examined as potential substrates for vaccinia TMP kinase and also for human TMP and GMP kinases. Molecular models obtained from structure-based docking rationalized the enzymatic data. All tested nucleotides are found surprisingly substrates of vaccinia TMP kinase and also of human GMP kinase. Interestingly, O(6)-methyl-dGMP is the only analog specific for the vaccinia enzyme. Thus, O(6)-Me-dGMP could be useful for designing new compounds of medical interest either in antipoxvirus therapy or in experimental combined gene/chemotherapy of cancer. These results also provide new insights regarding dGMP analog reaction with human GMP kinase and their slow ...
Biotin is required for enzymatic activity of several important carboxylases (Table 28.10). Biotin is first attached to a lysine residue of biotin carboxyl carrier protein (BCCP) by biotin- [propionyl-CoA-carboxylase (ATP-hydrolysing)] ligase (holocarboxylase [HCS], EC 6.3.4.10), which forms the biotinyl domain of the enzyme or separate subunit. The N1 position is subsequently carboxylated to form carboxy-biotin (Fig. 28.40), which is then able to transfer the carboxyl group to other substrates. The source of the carboxyl is either bicarbonate or decarboxylation of another substrate as is seen in transcarboxylation reactions.196 A typical carboxylation reaction mediated by biotin-BCCP is shown in Figure 28.41. The source of the carboxyl is bicarbonate with ATP supplying energy for the reaction. This is followed by the subsequent transfer of the carboxyl to the substrate with regeneration of the biotin-BCCP complex.. An interesting recent development is the finding that biotin is also attached to ...

Glycinamide ribonucleotide synthetase (GAR-syn) catalyzes the second step of the de novo purine biosynthetic pathway; the conversion of phosphoribosylamine,glycine, and ATP to glycinamide ribonucleotide (GAR), ADP, and Pi. GAR-syncontaining an N-terminal polyhistidine tag was expressed as the SeMetincorporated protein for crystallographic studies. In addition, the protein asisolated contains a Pro294Leu mutation. This protein was crystallized, and thestructure solved using multiple-wavelength anomalous diffraction (MAD) phasedetermination and refined to 1.6 A resolution. GAR-syn adopts an alpha/betastructure that consists of four domains labeled N, A, B, and C. The N, A, and Cdomains are clustered to form a large central core structure whereas the smaller B domain is extended outward. Two hinge regions, which might readily facilitateinterdomain movement, connect the B domain and the main core. A search ofstructural databases showed that the structure of GAR-syn is similar toD-alanine:D-alanine ...
The bifunctional human enzyme phosphoribosylaminoimidazole carboxylase and phosphoribosylaminoimidazolesuccinocarboxamide synthetase (PAICS) catalyzes two essential steps in the de novo purine biosynthesis pathway. PAICS is overexpressed in many cancers and could be a promising target for the development of cancer therapeutics. Here, using gene knockdowns and clonogenic survival and cell viability assays, we demonstrate that PAICS is required for growth and survival of prostate cancer cells. PAICS catalyzes the carboxylation of aminoimidazole ribonucleotide (AIR) and the subsequent conversion of carboxyaminoimidazole ribonucleotide (CAIR) and L-aspartate to N-succinylcarboxamide-5-aminoimidazole ribonucleotide (SAICAR). Of note, we present the first structures of human octameric PAICS in complexes with native ligands. In particular, we report the structure of PAICS with CAIR bound in the active sites of both domains and SAICAR bound in one of the SAICAR synthetase domains. Moreover, we report ...

Simple and easy to engineer metal-sensing molecules that are capable of differentiating metal ions and producing metal-specific signals are highly desirable. Metal ions affect the thermal stability of proteins by increasing or decreasing their resistance to unfolding. This work illustrates a new strategy for designing bivalent fluorescent fusion proteins capable of differentiating metal ions in solution through their distinct effects on a proteins thermal stability. A new dual purpose metal sensor was developed consisting of biotin protein ligase (BirA) from B. pseudomallei (Bp) fused to green fluorescent protein (GFP). When coupled with differential scanning fluorimetry of GFP-tagged proteins (DSF-GTP) for signal-transduction detection, Bp BirA-GFP yields distinct protein unfolding signatures with Zn(II) and Cu(II) ions in aqueous solutions. The limit of detection of the system is ∼1 μM for both metal species. The system can be used in a variety of high-throughput assay formats including ...

To develop, implement and improve these variety and seed regulations, the Ministry of Agriculture relies on an Advisory Committee: the Permanent Technical Committee for the Selection of Cultivated Plants (CTPS).. One of the primary missions of the CTPS is to assist and guide genetic progress by developing the technical rules for variety registration. These rules aim to ensure the best possible match between the objectives of variety users, civil society, public authorities, and the scientific and technical capacities of breeders, in order to meet the needs of sustainable and diverse agriculture. The CTPS proposes the listing and de-listing of plant varieties in the Official French Catalogue.. In France, the Ministry delegates seed production controls to various bodies: the Official Control Service (GNIS / SOC) for agricultural and vegetable plants, the Interprofessional Technical Centre for Fruits and Vegetables (CTIFL) for fruit trees, FranceAgriMer for Vine plants..
