Organelle- and Organ-Specific Isozymes of Euglena Gracilis and CatfishMo, Yeh-Chun 12 1900 (has links)
Two distinct compartmentalized isozymes of aldolase and triosephosphate isomerase were examined in the photoautotrophically and heterotrophically grown green alga Euglena gracilis. A comparison of the chemical and physical properties of the isozymes was carried out. Isozymes of phosphoglucose isomerase were isolated in homogeneous form from liver and muscle tissue of the fresh water catfish. The two organ-specific isozymes were essentially identical with respect to their molecular weights but exhibited different electrophoretic and kinetic properties, and amino acid compositions.

Isozymes and In Vivo Activity of Triosephosphate IsomeraseSnapka, Robert Morris 05 1900 (has links)
The distribution of isozymes of triosephosphate isomerase was normal in all human tissues examined. This finding argues against the existence of tissue-specific isozymes. Normal distributions of isozymes were also found in patients with cri-du-chat syndrome. Thus it is unlikely that a gene for triosephosphate isomerase is located on the short arm of chromosome five in man. When triosephosphate isomerases from a wide range of species were examined by starch gel electrophoresis, definite evolutionary patterns were found. Kinetic studies were conducted on human triosephosphate isomerase under conditions simulating the intracellular environment of the erythrocyte. Calculations using the kinetic parameters obtained indicate that even in triosephosphate isomerase deficiency disease, enough enzyme activity remains that the rate of glycolysis should not become inhibited.

Isozymic and cytological studies on populations of the introduced bee species, Megachile (Eutricharaea) rotundata and M. (Eutricharaea) apicalisChen, Xiaoshe 28 September 1992 (has links)
Thirteen New World populations of Megachile rotundata and M. apicalis and
two Old World populations of M. rotundata were analyzed at 23 enzyme loci using
cellulose acetate electrophoresis. Conventional and G- or C-banded karyotypes were
also examined in these populations. The principal findings are (1) No differences
were found in the level of heterozygosity between haplodiploid Megachile and that of
other diploid insects. This is the first record showing the mean heterozygosity in the
hymenopteran genus to be consistent with the mean of most other diploid insects. (2)
There was no difference in the level of heterozygosity nor the percent polymorphic
loci between males and females, and heterozygotes was discovered in males of the
two megachilid species studied. (3) The heterozygosity levels among New World
populations of M. rotundata and M. apicalis were similar, but both were more than
twice that of Old World rotundata analyzed. This is consistent with the expectations
of the founder-event models of both Carson and Templeton. (4) FST, the amount of
genetic differentiation among populations, was greater among New World populations
of apicalis sampled than among those of rotundata. The extensive commercialization
in rotundata may have tempered interpopulation differences which might had
occurred had the species been undisturbed. (5) Wrights "isolation by distance" model
is inapplicable to either of the two Megachile species. In rotundata, the high gene
flow level suggests that human commercial action may effectively disrupt any
opportunity for the development of locally adapted populations through selection. In
apicalis, little gene flow is present among the populations which is expected by both
Carson and Templeton models. The absence of any clinal pattern in apicalis probably
better reflects Templeton's transilience model. We believe that the random alteration
of major alleles, implicit in transilience, more readily accounts for the distinct local
populations we found in apicalis. (6) Chromosomal data suggest that both pericentric
inversions and deletions have been involved in karyotype evolution of the two species
and a primitive karyotype is proposed based on its ubiquitousness in all populations of
both species. / Graduation date: 1993
