beta-Lactamase K1 was purified from Klebsiella pneumoniae SC10436. It is very similar to the enzyme produced by Klebsiella aerogenes 1082E and described by Emanuel, Gagnon & Waley [Biochem. J. (1986) 234, 343-347]. An active-site peptide was isolated after labelling of the enzyme with tritiated beta-iodopenicillanate. A cysteine residue was found just before the active-site serine residue. This result could explain the properties of the enzyme after modification by thiol-blocking reagents. The sequence of the active-site peptide clearly established the enzyme as a class A beta-lactamase. [less ▲]

We present the discovery of a transiting exoplanet candidate in the K2 Field-1 with an orbital period of 9.1457 hours: EPIC 201637175b. The highly variable transit depths, ranging from $\sim$0\% to 1.3\%, are suggestive of a planet that is disintegrating via the emission of dusty effluents. We characterize the host star as an M-dwarf with $T_{\rm eff} \simeq 3800$. We have obtained ground-based transit measurements with several 1-m class telescopes and with the GTC. These observations (1) improve the transit ephemeris; (2) confirm the variable nature of the transit depths; (3) indicate variations in the transit shapes; and (4) demonstrate clearly that at least on one occasion the transit depths were significantly wavelength dependent. The latter three effects tend to indicate extinction of starlight by dust rather than by any combination of solid bodies. The K2 observations yield a folded light curve with lower time resolution but with substantially better statistical precision compared with the ground-based observations. We detect a significant ``bump' just after the transit egress, and a less significant bump just prior to transit ingress. We interpret these bumps in the context of a planet that is not only likely streaming a dust tail behind it, but also has a more prominent leading dust trail that precedes it. This effect is modeled in terms of dust grains that can escape to beyond the planet's Hill sphere and effectively undergo `Roche lobe overflow', even though the planet's surface is likely underfilling its Roche lobe by a factor of 2.

In the inner ear, the excitatory amino acid glutamate is a proposed neurotransmitter acting at the synapse between hair cells and afferent auditory neurons. Using cultures of 5-day-old rat auditory neurons, we show that the afferent auditory neuronal population can be divided, on the basis of its sensitivity to the neuronotoxic effect of glutamate and its analogs, in at least 3 subpopulations, one responding to N-methyl-D-aspartate (NMDA), one responding to kainate and a third minor one unresponsive to NMDA, kainic acid and glutamate. No toxic effect of quisqualate is observed. The use of specific antagonists (kynurenate and 2-amino-5-phosphonovalerate (DAP-5) demonstrates the specificity of the receptors to the excitatory amino acids on the afferent auditory neurons. Afferent auditory neurons from adult rats can also be cultured and in these preparations only the large neurons are sensitive to glutamate, kainate and NMDA while the small neurons are not responsive, suggesting that a glutamatergic neurotransmission occurs only at this synapse between the inner hair cells and the large radial afferent auditory neurons. We also show that, in vitro, the organ of Corti releases, in response to an increased potassium concentration and in the presence of calcium, a toxic activity for the afferent auditory neurons that is antagonized by kynurenate and DAP-5. Pathophysiological implications are discussed. [less ▲]

Although the interactions between sex steroids and GnRH have been extensively studied, little is known about the mechanism of estradiol (E2) effects on GnRH secretion. In the present study, we used retrochiasmatic hypothalamic explants of 50-d-old male rats, and we observed that E2 significantly increased the glutamate-evoked GnRH secretion in vitro within 15 min in a dose-dependent manner. E2 also significantly increased the L-arginine-evoked GnRH secretion. E2 effects were time dependent because the initially ineffective 10(-9) M concentration became effective after 5 h of incubation. The E2 effects involved the estrogen receptor (ER) alpha because they were similarly obtained with the specific ER alpha agonist 1,3,5-tris(4-hydroxyphenyl)-4-propyl-1H-pyrazole. The use of glutamate receptor agonists and antagonists indicated that E2 effects on GnRH secretion evoked by both glutamate and L-arginine involved the 2-amino-3-hydroxy-5-methyl-4-isoxazol propionic acid/kainate receptors. Similar E2 effects on the kainate-evoked secretion were observed throughout development in both sexes. The observation of similar E2 effects using explants containing the median eminence alone indicated that the median eminence was a direct target for E2 rapid effects on the glutamate-evoked GnRH secretion. The signaling pathways involved in E2 effects included an increase in intracellular calcium and the activation of protein kinase A, protein kinase C, and MAPK. It is concluded that E2 can stimulate the glutamate- and nitric oxide-evoked GnRH secretion in vitro through a rapid pathway involving the ER and kainate receptor as well as through a slower mechanism responding to lower E2 concentrations.
