To determine the structural basis for binding subtype selective agonists in the beta-adrenergic receptor (beta AR), we examined the interaction of the mutant beta 2AR and chimeric beta 1/beta 2AR with a selective beta 2AR agonist, TA-2005 (8-hydroxy-5-[(1R)-1-hydroxy-2-[N-[(1R)-2-(p-methoxyphenyl)-1-methyle thy l] amino]ethyl] carbostyril hydrochloride). The beta 2AR mutant with Ala substitute...

Carcinogenic formaldehyde is produced by endogenous protein oxidation and various exogenous sources. With formaldehyde being both ubiquitous in the ambient environment and one of the most common reactive carbonyls produced from endogenous metabolism, quantifying formaldehyde exposure is an essential step in risk assessments. We present in this study an approach to assess the risk of exposure to...
