A study of baboon hemoglobin.
American Journal of Physical Anthropology
|May 1, 1975
Summary
Baboon hemoglobin electrophoresis reveals a homogeneous protein across species, distinct from other primates. Subtle differences in nonhemoglobin fractions between Papio anubis and Papio cynocephalus may indicate variations in amino acid sequences, aiding classification.
Area of Science:
- Primate genetics and evolution
- Biochemistry and molecular biology
Background:
- Hemoglobin electrophoresis is a key technique in studying primate taxonomy.
- Previous research has established general patterns of hemoglobin variation in non-human primates.
Purpose of the Study:
- To analyze the electrophoretic patterns of hemoglobin in a large cohort of baboons (409 individuals).
- To compare baboon hemoglobin with that of other monkey species.
- To investigate potential variations within baboon species, specifically Papio anubis and Papio cynocephalus.
Main Methods:
- Electrophoretic analysis was performed on hemoglobin samples from 409 baboons.
- Comparative electrophoresis was conducted against hemoglobin from other monkey species.
- Analysis focused on both hemoglobin and nonhemoglobin fractions.
Main Results:
- Baboon hemoglobin demonstrated electrophoretic homogeneity overall.
- Baboon hemoglobin exhibited distinct electrophoretic mobility compared to other monkey species.
- A notable difference in the electrophoretic mobility of the nonhemoglobin fraction was observed between Papio anubis and Papio cynocephalus.
Conclusions:
- Baboon hemoglobin is largely conserved across species, differing significantly from other primates.
- The observed nonhemoglobin fraction differences suggest potential variations in amino acid sequences between Papio anubis and Papio cynocephalus.
- These electrophoretic findings can be valuable for taxonomic classification, especially in ambiguous cases.

Gene Families
10.2K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Globular and Fibrous Proteins
48.6K
Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

Wald-Wolfowitz Runs Test II
649
The Wald-Wolfowitz runs test, commonly referred to as the runs test, is a nonparametric test used to assess the randomness of ordered data. The test evaluates the number of runs, which are consecutive sequences of similar elements within the data. If the number of runs is significantly higher or lower than expected, the data is considered non-random, indicating a detectable pattern or structure.
For binary data, runs are identified using symbols such as + and −, or equivalently, 1s and 0s. In...

Hemoglobin
9.9K
Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...

The ABO Blood Group
6.6K
The ABO blood group system is a critical element of transfusion medicine, essential for determining blood compatibility in transfusions and organ transplants. It is based on specific antigens, or agglutinogens, present on the surface of red blood cells (RBCs) and corresponding antibodies, or agglutinins, in the blood plasma.
Antigens in the ABO Blood Group System
Antigens are substances that can trigger an immune response, leading to the production of antibodies. In the ABO blood group system,...

Oxygen Transport in the Blood
8.3K
Hemoglobin (Hb) is a crucial molecule in the human body, consisting of four polypeptide chains, each bound to an iron-containing heme group. This unique structure enables hemoglobin to bind to oxygen, with each molecule capable of combining with four molecules of oxygen, leading to rapid and reversible oxygen loading. When fully loaded with oxygen, it is called oxyhemoglobin, while hemoglobin that has released oxygen is called reduced hemoglobin or deoxyhemoglobin. As hemoglobin binds oxygen,...
