Differential synthesis of polypeptides during morphogenesis of Mucor. 1980

W R Hiatt, and C B Inderlied, and P S Sypherd

The extent of differential gene expression during morphogenesis of Mucor racemosus was investigated by two-dimensional polyacrylamide gel electrophoresis of neutral and acidic polypeptides. Cellular proteins were labeled with [35S]methionine in cells growing in either the yeast or hyphal form, or in yeast cells undergoing the transition of hyphae. The results showed that of the 400 to 500 polypeptides resolved by electrophoresis, relatively few were specific to one or the other morphological form. The major change in the patterns of proteins synthesized during morphogenesis was a change in rates of synthesis of individual polypeptides. Experiments in which morphogenesis was affected under aerobic or anaerobic conditions showed that the majority of changes in the protein patterns were associated with morphogenesis and were not a specific response to O2.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D009024	Morphogenesis	The development of anatomical structures to create the form of a single- or multi-cell organism. Morphogenesis provides form changes of a part, parts, or the whole organism.
D009089	Mucor	A genus of zygomycetous fungi of the family Mucoraceae, order Mucorales. It is primarily saprophytic, but may cause MUCORMYCOSIS in man from spores germinating in the lungs.	Mucors
D010452	Peptide Biosynthesis	The production of PEPTIDES or PROTEINS by the constituents of a living organism. The biosynthesis of proteins on RIBOSOMES following an RNA template is termed translation (TRANSLATION, GENETIC). There are other, non-ribosomal peptide biosynthesis (PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT) mechanisms carried out by PEPTIDE SYNTHASES and PEPTIDYLTRANSFERASES. Further modifications of peptide chains yield functional peptide and protein molecules.	Biosynthesis, Peptide
