The correct folding of a protein is a pre-requirement for its proper posttranslational modification. The Escherichia coli Sec pathway, in which preproteins, in an unfolded, translocation-competent state, are rapidly secreted across the cytoplasmic membrane, is commonly assumed to be unfavorable for their modification in the cytosol. Whether posttranslationally modified recombinant preproteins c...
Alkyl branching at the β position of a polyketide intermediate is an important variation on canonical polyketide natural product biosynthesis. The branching enzyme, 3-hydroxy-3-methylglutaryl synthase (HMGS), catalyzes the aldol addition of an acyl donor to a β-keto-polyketide intermediate acceptor. HMGS is highly selective for two specialized acyl carrier proteins (ACPs) that deliver the donor...
/3-Hydroxyacyl acyl carrier protein (ACP) dehydrase has been purified 2900-fold from extracts of Escherichia coli. The enzyme catalyzes the reversible dehydration of /3-hydroxyacyl-ACP thioesters to yield specifically tram-2-enoylACP products. It is active with frans-2-enoyl-ACP thioesters of chain lengths from 4 through 16 carbon atoms. The enzyme catalyzes the hydration of cis-5frans-2-dodeca...
OBJECTIVES There is limited evidence of the impact of advance care planning (ACP) on outcomes. We conducted a retrospective cohort study on deaths of all patients known to a hospice in a 2.5-year period to see if use of ACP affected actual place of death, hospital use and cost of hospital care in the last year. RESULTS 969 patients were included. 550 (57%) people completed ACP. 414 (75%) achi...
We report the isolation of Vibrio harveyi acyl carrier protein (ACP) and cloning of a 3,973-bp region containing the fabG (encoding 3-ketoacyl-ACP reductase, 25.5 kDa), acpP (encoding ACP, 8.7 kDa), fabF (encoding 3-ketoacyl-ACP synthase II, 43.1 kDa), and pabC (encoding aminodeoxychorismate lyase, 29.9 kDa) genes. Predicted amino acid sequences were, respectively, 78, 86, 76, and 35% identical...
Acyl carrier protein (ACP), a small protein essential for bacterial growth and pathogenesis, interacts with diverse enzymes during the biosynthesis of fatty acids, phospholipids, and other specialized products such as lipid A. NMR and hydrodynamic studies have previously shown that divalent cations stabilize native helical ACP conformation by binding to conserved acidic residues at two sites (A...
Key components of advance care planning (ACP) for the elderly include choosing a surrogate decision maker, identifying personal values, communicating with surrogates and clinicians, documenting wishes in advance directives, and translating values and preferences for future medical care into medical orders. ACP often involves multiple brief discussions over time. This article outlines common ben...
In plants, fatty acid biosynthesis takes place in the plastid. The primary products of fatty acid biosynthesis are palmitoylACP2 (16:0-ACP) and stearoyl-ACP (18:0-ACP). The soluble plastidic enzyme stearoyl-ACP desaturase (EC 1.14.99.6) introduces the first cis-double bond into stearoyl-ACP between carbons 9 and 10 to produce oleoyl-ACP (18:19-ACP). Further desaturation of palmitic or oleic aci...
OBJECTIVE To improve outpatient advanced care planning (ACP) for adults with congenital/pediatric heart disease followed in a pediatric heart failure (HF) and transplant clinic through quality improvement (QI) methodology. DESIGN A one-year QI project was completed. We conducted quarterly chart reviews and incorporated feedback from the providers to direct subsequent interventions. PATIENTS...
background and aims. remineralization of incipient caries is one of the goals in dental health care. the present study aimed at comparing the effects of casein phosphopeptide-amorphous calcium phosphate complex (cpp-acp), remin pro®, and 5% sodium fluoride varnish on remineralization of enamel lesions. materials and methods. in this in vitro study, 60 enamel samples were randomly allocated to s...
