Functional Differences in Yeast Protein Disulfide Isomerases
PDI1 is the essential gene encoding protein disulfide isomerase in yeast. The Saccharomyces cerevisiae genome, however, contains four other nonessential genes with homology to PDI1: MPD1, MPD2, EUG1, and EPS1. We have investigated the effects of simultaneous deletions of these genes. In several cases, we found that the ability of the PDI1 homologues to restore viability to a pdi1-deleted strain...
متن کاملIdentification of an atypical membrane protein involved in the formation of protein disulfide bonds in oxygenic photosynthetic organisms.
The evolution of oxygenic photosynthesis in cyanobacteria nearly three billion years ago provided abundant reducing power and facilitated the elaboration of numerous oxygen-dependent reactions in our biosphere. Cyanobacteria contain an internal thylakoid membrane system, the site of photosynthesis, and a typical Gram-negative envelope membrane system. Like other organisms, the extracytoplasmic ...

where DaUk converges strongly to Dau in L2(Q). Furthermore, daf(uk)Dv converges strongly to da,,(u)Dv in L2(Q) by dominated convergence. Hence, each term in the sum for a (u k, V) converges to the corresponding term in the sum for a(u, v), (G(uk), v)m . (G(u), v)m for each v in V, and the proof of Lemma 3 is complete. Proof of Theorem 1: By Lemma 2, it suffices to show that the mapping G is one...
متن کاملFunctional genomic analysis of the HY2 family of ferredoxin-dependent bilin reductases from oxygenic photosynthetic organisms.
Phytobilins are linear tetrapyrrole precursors of the light-harvesting prosthetic groups of the phytochrome photoreceptors of plants and the phycobiliprotein photosynthetic antennae of cyanobacteria, red algae, and cryptomonads. Previous biochemical studies have established that phytobilins are synthesized from heme via the intermediacy of biliverdin IX alpha (BV), which is reduced subsequently...
متن کاملThioredoxin-interacting protein regulates protein disulfide isomerases and endoplasmic reticulum stress
The endoplasmic reticulum (ER) is responsible for protein folding, modification, and trafficking. Accumulation of unfolded or misfolded proteins represents the condition of ER stress and triggers the unfolded protein response (UPR), a key mechanism linking supply of excess nutrients to insulin resistance and type 2 diabetes in obesity. The ER harbors proteins that participate in protein folding...
