“…Walterinnesia morgani (Mocquard, 1905) (Desert Black Cobra), a venomous snake, is mainly encountered in the Middle East including southeastern Türkiye, Iran, Iraq, Syria, Saudi Arabia, and Kuwait (Nilson & Rastegar-Pouyani, 2007). It is is the only member of the Elapidae family in Türkiye, occurring in Sanliurfa and Kilis provinces (Üçeş & Yıldız, 2020;Yıldız, 2020). Populations of W. morgani had known as W. aegyptia until it was described as a separate species (by combination) in 2007 (Nilson & Rastegar-Pouyani, 2007).…”

Snake venom contains various bioactive proteins and peptides, of which enzymes make up a significant portion. Desert Black Cobra (Walterinnesia morgani) is a venomous snake distributed mainly in the Middle East including southeastern Türkiye. The aim of the present study is to investigate the key enzyme activities and protein profile of W. morgani venom originating from Sanliurfa province. After the determination of the protein content, the venom sample was subjected to enzymatic activity assays to assess phospholipase A2, protease, ʟ-amino acid oxidase, hyaluronidase, 5′-nucleotidase and, phosphodiesterase activities by a spectrophotometry-based method. Protease activity was also assessed by gelatin zymography. Additionally, the fibrinogenolytic activity of the venom was evaluated using fibrinogen zymography and SDS-PAGE methods. The protein profile was obtained by SDS-PAGE (both reduced and non-reduced) and reversed-phase HPLC methods. According to the results, 11 protein bands between approximately 12-240 kDa were observed on non-reduced SDS-PAGE gel while there were nine bands between 12-140 kDa on the reduced gel. Venom proteins of W. morgani were found predominantly between 25-12 kDa. Proteins were separated into at least 19 major and minor protein groups (peaks) by HPLC analysis. The venom of W. morgani showed all enzyme activities at varying levels.

In this study, amphibian and reptile diversity in the province of Van (eastern Anatolia, Turkey) was surveyed. For this purpose, four herpetological excursions (20 days in total) were conducted covering all the districts of the province in 2014. In this paper, up-to-date herpetofaunal inventory of Van Province, including two urodelian, four anuran, two chelonian, 15 saurian (lizards), and 14 ophidian (snakes) species (six amphibians and 31 reptiles in total) is presented. To the best of our knowledge, Salamandra infraimmaculata, Heremites auratus, Dolichophis jugularis, Eirenis modestus, and Telescopus fallax were recorded for the first time in the province of Van. Additionally, the first published print record of Stellagama stellio in Van Province is presented. The major threat to the herpetofaunal diversity in surveyed habitats was found as human-origin habitat degradation. With the georeference database obtained in this study, it will be possible to determine the actual distribution ranges of the species and to guide decision-makers. The results of the study will provide a useful basis for future monitoring studies and distribution information will contribute to the conservation of the species of interest.
