His primary scientific interests are in Molecular biology, Biochemistry, Nucleoside, Purine nucleoside phosphorylase and Adenosine. His Molecular biology research is multidisciplinary, relying on both Mutant, Gene, Toxicity and Intracellular. Biochemistry is closely attributed to Protozoa in his study.
His Nucleoside study which covers Equilibrative nucleoside transporter that intersects with Membrane transport protein. His research in Purine nucleoside phosphorylase focuses on subjects like Adenosine deaminase, which are connected to Nucleotide salvage, Pyrimidine nucleoside transport, Equilibrative nucleoside transporter 1 and Equilibrative nucleoside transporter 2. As part of one scientific family, Buddy Ullman deals mainly with the area of Adenosine, narrowing it down to issues related to the Thymidine, and often Cytidine, Pyrimidine and Clone.
His primary areas of study are Biochemistry, Molecular biology, Nucleoside, Purine and Mutant. His study ties his expertise on Leishmania donovani together with the subject of Biochemistry. His Leishmania donovani study combines topics from a wide range of disciplines, such as Polyamine, Ornithine decarboxylase and Microbiology.
Buddy Ullman works mostly in the field of Molecular biology, limiting it down to topics relating to Phosphoribosyltransferase and, in certain cases, Adenine phosphoribosyltransferase. His Nucleoside study incorporates themes from Nucleoside transporter, Equilibrative nucleoside transporter, Equilibrative nucleoside transporter 2, Inosine and Thymidine. His study explores the link between Purine and topics such as Nucleotide that cross with problems in Pyrimidine.
Biochemistry, Molecular biology, Leishmania donovani, Purine and Purine metabolism are his primary areas of study. Polyamine, Nucleotide, Arginase, Membrane transport protein and Spermidine are the subjects of his Biochemistry studies. His Molecular biology research integrates issues from Inosine-5′-monophosphate dehydrogenase, Hypoxanthine-guanine phosphoribosyltransferase, Mutant, Hypoxanthine and Adenine phosphoribosyltransferase.
His Mutant research is multidisciplinary, relying on both Deoxyguanosine and Homologous recombination. Buddy Ullman has included themes like Wild type, Ornithine decarboxylase and Deoxycoformycin in his Leishmania donovani study. His research in Purine intersects with topics in Nucleotide salvage, Equilibrative nucleoside transporter 2, Xanthine, Nucleoside and Purine riboswitch.
Buddy Ullman spends much of his time researching Biochemistry, Spermidine, Polyamine, Putrescine and Leishmania donovani. Buddy Ullman has researched Biochemistry in several fields, including Molecular biology and Leishmania. In most of his Molecular biology studies, his work intersects topics such as Nucleoside transporter.
His Spermidine study integrates concerns from other disciplines, such as Membrane transport protein and Ornithine decarboxylase. His Polyamine research incorporates themes from Trypanosoma cruzi, Cell biology and Spermine. His Leishmania donovani research is multidisciplinary, incorporating elements of Purine/pyrimidine metabolism, Adenylosuccinate lyase deficiency, Microbiology and Adenylosuccinate, Adenylosuccinate synthase.
