A study was completed to determine the extent of the
protein changes occurring in ground beef stored at
2°C for 10 days.
Sections of semitendinosus muscle were obtained
immediately after the slaughter of three beef animals.
Each section was divided into two equal portions, one of
which was ground and...
Investigations were conducted to determine whether the low molecular weight nitrogen compounds and the extra protein complex of bovine psoas major muscle were altered during a 12-day aging period.
Electrophoretic studies of soluble proteins either before or after gel filtration on Sephadex G-25 columns indicated that the soluble proteins were...
The electrophoretic behavior of sarcoplasmic proteins was
investigated by the use of vertical acrylamide gel electrophoresis.
The first part of the study was concerned with the separation of
sarcoplasmic proteins extracted at different times of post-mortem
aging. Electrophoresis of the sarcoplasmic extracts by the discontinuous
technique, using ten percent acrylamide...
The influence of polyphosphates upon the emulsification of
enzymatic hydrolyzates of casein and lactalbumin and upon salt-soluble
meat proteins was determined by a model system in which
oil-in-water emulsions were formed.
Sodium acid pyrophosphate, sodium tripolyphosphate and
sodium hexametaphosphate were mixed together in a weight ratio
of 4:2:4, respectively, to...
The collagen content and composition of collagens in
different age classes of shrimp were determined. Their
physical and chemical characteristics were investigated.
The interrelationship of shrimp size and muscle collagen
content to raw and cooked meat yield was established.
Total collagen content for three lots of round shrimp
with weights...
The DNA-binding domains of E. coli uracil-DNA glycosylase (Ung) and human replication protein A (hRPA) were studied using a general protocol developed in our laboratory for probing protein-DNA interactions. The procedure involves purification and mass spectrometric analysis of the nucleopeptide-products of a tryptically digested UV-crosslinked protein-nucleic acid complex. In the...
Cells represent microcosms of spatial and temporal structural organization, with the achievement of internal spatial organization relying upon a collection of macromolecular motor complexes to transport and localize components throughout the cell. Cytoplasmic dynein is one such motor complex, and is the principal ATP-dependent motor for retrograde transport along microtubules...
The symbiotic sea anemone Exaiptasia diaphana (Aiptasia) is a model organism used to better understand cnidarian-algal symbiosis and coral bleaching (dysbiosis). Many biological processes are hypothesized to be involved in coral dysbiosis, and the innate immunity is a key area of interest. Rab proteins are small proteins with GTPase domains,...
