/iron-sulfur protein methyltransferase (MeTr)
The methyltetrahydrofolate:corrinoid/iron-sulfur protein methyltransferase (MeTr) enzyme was originally isolated from the acetogenic bacteria Moorella (formerly Clostridium) thermoaceticum [612]. This bacterium, as some other anaerobic organisms, can obtain its entire carbon and energy source from CO or H2/CO2 by the Wood-Ljungdahl or acetyl-CoA pathway [613-615]. Initially, CO2 is reduced to f...
متن کاملHuman amidophosphoribosyltransferase. An oxygen-sensitive iron-sulfur protein.
Glutamine 5-phosphoribosyl-1-pyrophosphate amidotransferase (EC 2.4.2.14), amidophosphoribosyltransferase, was partially purified from human placenta. Upon exposure to oxygen, both the glutamine and ammonia activities were lost in parallel. Inactivation by oxygen increased as the temperature of incubation rose and the partial pressure of oxygen increased. Molecular oxygen rather than a radical ...
متن کاملSNAP-25, a Known Presynaptic Protein with Emerging Postsynaptic Functions
A hallmark of synaptic specializations is their dependence on highly organized complexes of proteins that interact with each other. The loss or modification of key synaptic proteins directly affects the properties of such networks, ultimately impacting synaptic function. SNAP-25 is a component of the SNARE complex, which is central to synaptic vesicle exocytosis, and, by directly interacting wi...
متن کاملSufU is an essential iron-sulfur cluster scaffold protein in Bacillus subtilis.
Bacteria use three distinct systems for iron-sulfur (Fe/S) cluster biogenesis: the ISC, SUF, and NIF machineries. The ISC and SUF systems are widely distributed, and many bacteria possess both of them. In Escherichia coli, ISC is the major and constitutive system, whereas SUF is induced under iron starvation and/or oxidative stress. Genomic analysis of the Fe/S cluster biosynthesis genes in Bac...
متن کاملAn Ipomoea batatas Iron-Sulfur Cluster Scaffold Protein Gene, IbNFU1, Is Involved in Salt Tolerance
Iron-sulfur cluster biosynthesis involving the nitrogen fixation (Nif) proteins has been proposed as a general mechanism acting in various organisms. NifU-like protein may play an important role in protecting plants against abiotic and biotic stresses. An iron-sulfur cluster scaffold protein gene, IbNFU1, was isolated from a salt-tolerant sweetpotato (Ipomoea batatas (L.) Lam.) line LM79 in our...
