Hydrogen bonding network as a logic gate

A circuit consisting of four- and five-terminal block elements is developed to imitate the behavior of hydrogen bonding networks in the β-lactamase protein. The circuit is implemented in Cadence Spectre to simulate its signal processing capabilities. The analysis shows that circuit outputs have logic levels for the current. The simulations show that the circuit can simultaneously invert and repeat signals, i.e. parts of the protein operate as logic gates.
