On the one hand, this type of organizational structure benefits from having individuals entirely dedicated to one function. In some cases, there can be cost savings and efficiency gains in combining functions in this way. However, this type of organizational structure is prone to conflict.
The alpha subunit (RpoA) initiates RNAP assembly by dimerising to form a platform on which the beta subunits can interact. The alpha subunit consists of a N-terminal domain (NTD) and a C-terminal domain (CTD), connected by a short linker.
Alpha amanitin is a molecule made from the âdeath capâ mushroom and is a known potent inhibitor RNA polymerase. One single mushroom could very easily lead to a fast death in 10 days. The mechanism of action is that alpha amanitin inhibits RNA polymerase at both the initiation and elongation states of transcription.
