The biochemical composition of the invasive ctenophore, Mnemiopsis leidyi from the southern Caspian Sea was analysed in terms of total fractions of protein, lipid, ninhydrin-positive substances (NPS), polysaccharides ( PS) and low molecular-weight carbohydrates (LMC). The sum of organic substances per gram dry weight was 84.2 mg g(-1). Protein was the major organic fraction followed by lipid and NPS. The NPS/protein and LNC/PS ratio were 0.45 and 0.50 respectively. Starvation of M. leidyi for a 5-day period resulted in a 32.7% reduction of total organic content. These data will be important in evaluating the feeding condition of M. leidyi specimens from the field.

Bioproduction, structure elucidation and in vitro antiproliferative effect of eumelanin pigment from Streptomyces parvus BSB49 Bayram, Sinan; Dengiz, Çağatay; GERÇEK, Yusuf Can; ÇETİN, İdil; TOPÇUL, Mehmet Rıfkı (Springer Science and Business Media LLC, 2020-01-01) In this study, the structure of the purified extracellular eumelanin pigment isolated from Streptomyces spp. was elucidated by detailed analysis via two different spectroscopic techniques (FT-IR and NMR). In vitro antiproliferative effects of eumelanin were evaluated on HeLa cell line. These experiments were carried out with the evaluation of the parameters including cell viability, cell index, and mitotic index. With the cell viability and cell index, IC50 concentration of eumelanin was determined as 10 μM...
Proteome-wide analysis of the functional roles of Bacilysin biosynthesis in Bacillus subtilis Taşkın Aras, Aslı; Özcengiz, Gülay; Department of Biology (2010) The members of the genus Bacillus produce a wide variety of secondary metabolites with antimetabolic and pharmacological activities. Most of these metabolites are small peptides that have unusual components and chemical bonds and synthesized nonribosomally by multifunctional enzyme complexes called peptide synthetases. Bacilysin, being produced and excreted by certain strains of Bacillus subtilis, is one of the simplest peptide antibiotics known. It is a dipeptide with an N-terminal L-alanine and an unusual...

Proteome-wide analysis of the role of expression of bacilysin operon on idiophase physiology of B. Subtilis Demir, Mustafa; Özcengiz, Gülay; Department of Biology (2013) The members of the genus Bacillus produce a wide variety of secondary metabolites with antimetabolic and pharmacological activities. These metabolites are mostly small peptides and have unusual components and chemical bonds. These metabolites are synthesized nonribosomally by multifunctional enzyme complexes called peptide synthetases. One of those small peptides, bacilysin, is a dipeptide antibiotic composed of L-alanine and L-anticapsin which is produced and excreted by certain strains of Bacillus subtili...
Cytochrome P4502B-type protein from feral leaping mullet (Liza Saliens) liver microsomes: its isolation and biochemical and immunological characterization Bozcaarmutlu, Azra; Arınç, Emel; Department of Biochemistry (2002) Cytochrome P450s constitute a superfamily of hemoproteins that play important roles in oxidative metabolism of endogenous and exogenous compounds, and serve as catalysts that are significant in numerous and diverse biological pathways. The extent to which these various pathways or functions occur in different animal groups depend on a large degree on the participation of different P450 proteins present, their catalytic function and their regulation. Cytochrome P4502B subfamily is generally associated with d...
