Abstract

An understanding of the underpinning physiology and biochemistry of animals is essential to properly understand the impact of anthropogenic changes and natural catastrophes upon the conservation of endangered species. An observation on the tissue location of the key respiratory protein, myoglobin, now opens up new opportunities for understanding how hypoxia tolerance impacts on diving lifestyle in turtles. The respiratory protein, myoglobin has functions other than oxygen binding which are involved in hypoxia tolerance, including metabolism of reactive oxygen species and of the vascular function by metabolism of nitric oxide. Our work aims to determine whether myoglobin expression in the green turtle exists in multiple non muscle tissues and to confirm the hypothesis that reptiles also have a distributed myoglobin expression which is linked to the hypoxiatolerant trait. This initial work in turtle hatch Chelonia mydas confirms the presence of myoglobin transcriptin brain, heart and liver tissues. Furthermore, it will serve as a tool for completing the sequence and generating an in situ hybridization probe for verifying of cell location in expressing tissues.

Abstract

Thiamine has fundamental role in energy metabolism. The organs mostly sensitive to the lack of thiamine levels in the body are the nervous system and the heart. Thiamine deficiency causes symptoms of polyneuritis and cardiovascular diseases. Because of its importance in the metabolism of carbohydrates, we need to measure the levels of thiamine in the body fluids by using an easy and inexpensive way without compromising the sensitivity and selectivity. An option to it is thiamine measurement based on the principle of which is analogous to ELISA, in which a thiamine binding protein (TBP) act by replacing antibodies. The presence of TBP in several seeds have been reported by previous researchers, but the presence of TBP in mung beans has not been studied. This study was aimed to isolate and purify TBP from mung bean. The protein was isolated from mung beanĀ  through salting out by ammonium sulphate of 40, 70, and 90% (w/v). TBP has a negative charge as shown by cellulose acetate electrophoresis. The result obtained after salting out by ammonium sulphate was further purified bymeans of DEAE-cellulose chromatography and affinity chromatography. In precipitation of 90% of salting out method, one peak protein was obtained by using affinity chromatography. The protein was analyzed by SDS PAGE electrophoresis. The result of SDS PAGE electrophoresis showed that TBP has a molecular weight of 72.63 kDa.
