A novel serine protease from strawberry (Fragaria ananassa): Purification and biochemical characterization

Alıcı, Esma Hande; Arabacı, Gülnur (ELSEVIER, 2018)

In this study, a protease enzyme was purified from strawberry by using Sepharose-4B-L-tyrosine-p-amino benzoic acid affinity chromatography. The molecular weight of pure protease was determined 65.8 kDa by SDS-PAGE. The ...

Bilgiçli, Ahmet Turgut; Alıcı, Esma Hande; Yaraşır, Meryem Nilüfer; Arabacı, Gülnur; Kandaz, Mehmet (TAYLOR & FRANCIS LTD, 2015)

The tetra - or -thiophene substituted metal and metal-free phthalocyanines (Pcs) M[Pc(-OCH(2)Thiopen)(4)] and M[Pc(-OCH(2)Thiopen)(4)] {(-ThMet-MPc), (-ThMet-MPc) [ThMet: Thiophene methoxy], M=Zn(II), Co(II) and, 2H} were ...
Antioxidant properties of water-soluble phthalocyanines containing quinoline 5-sulfonic acid groups

Günsel, Armağan; Alıcı, Esma Hande; Bilgiçli, Ahmet Turgut; Arabacı, Gülnur; Arabacı, Gülnur; Yaraşır, Meryem Nilüfer (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2019)

In the present study, the antioxidant properties of peripherally and nonperipherally water-soluble tetra (quinoline 5-sulfonic acid) substituted metal-free (1, 2), Zn(II) (3, 4), Co(II) (5, 6), and Mn(III)Cl (7, 8) ...
Formation, characterization, aggregation, fluorescence and antioxidant properties of novel tetrasubstituted metal-free and metallophthalocyanines bearing (4-(methylthio)phenoxy) moieties

Nurdan Yildirim; Bilgiçli, Ahmet Turgut; Alıcı, Esma Hande; Arabacı, Gülnur; Yaraşır, Meryem Nilüfer (ELSEVIER SCIENCE BV, 2017)

The synthesis and characterization of peripherally tetra 4-(methylthio)phenoxy substituted metal-free(2), Zn(II) (3) and Co(II) (4) phthalocyanine derivatives were reported. These newly synthesized phthalocyanine derivatives ...
Partial Purification and Characterization of Polyphenol Oxidase from the Wild Edible Mushroom Lepiota Procera Using Three-Phase Partitioning

Neslihan Saki; Mustafa Akin; Alıcı, Esma Hande; Arabacı, Gülnur (WALTER DE GRUYTER GMBH, 2018)

Polyphenol oxidase (PPO) from the wild edible mushroom Lepiota procera is partially purified and biochemically characterized using three-phase partitioning (TPP), which is an easily applied and effective method. This method ...
Purification of polyphenol oxidase from borage (Trachystemon orientalis L.) by using three-phase partitioning and investigation of kinetic properties

Alıcı, Esma Hande; Arabacı, Gülnur (ELSEVIER, 2016)

In this study a Polyphenol oxidase from borage plant was purified with 3.59-fold enrichment in the specific activity and 68.75% recovery of the total activity by using three-phase partitioning purification technique for ...
