When methionine is in excess, Hcy is directed to the transulphuration pathway, where it is irreversibly sulfoconjugated to cysteine by cystathionine B-synthase with vitamin B 6 as a cofactor. Hcy is also remethylated in a methionine-conserving pathway. This process requires methionine synthase, vitamin B 12 as a cofactor, and methyltetrahydrofolate as a cosubstrate. The methionine-conserving pathway requires folic acid and methyltetrahydrofolate reductase (MTHFR).
Wire-transferred funds typically appear within 24 to 48 hours. A wire transfer is a bank-to-bank transaction in which a sender goes to his bank and has money transferred from his account to another person's account at the same bank or in a different bank. Typically, an interbank transfer occurs in the same-day.
Fault clearing time is the sum of relay time and circuit breaker time. The rapid fault clearing of extra high voltage transmission lines improves the power system stability. Hence, faster relying and fast circuit breaker are preferred for extra high voltage transmission lines, where the circuit breaker time being in order of 2.5 cycles.
