There is a report of the EGFR tyrosine kinase domain being expressed in E. coli as a GST fusion (see the link). That group used BL21 codon plus RIL.

XRP token and Ripple Payment Protocol are Different. Ripple is a global settlement network which allows banks to transfer money and settle international payments in different currencies. As more banks use Ripple protocol, it is becoming more valuable. Contrary to popular belief, XRP currency is different than the Ripple protocol. XRP is a token or a native currency that works under Ripple Transaction Protocol. XRP protects the Ripple network from DDOS attacks, and prevents spam.
Ripple relies on a common shared ledger, which is a distributed database storing information about all Ripple accounts. The network is managed by a network of independent validating servers that constantly compare their transaction records.. Servers could belong to anyone, including banks or market makers.ithin the networkâs currency exchange, XRP are traded freely against other currencies, and its market price fluctuates against dollars, euros, yen, bitcoin, etc. Ripple's design focus is as a currency exchange and a distributed-RTGS, as opposed to emphasizing XRP as an alternative currency.
