TRNA (cytidine56-2'-O)-methyltransferase

TRNA (cytidine56-2'-O)-methyltransferase is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand TRNA (cytidine56-2'-O)-methyltransferase rather than just read about it. In short: tRNA (cytidine56-2'-O)-methyltransferase (EC 2.1.1.206, aTrm56, tRNA ribose 2'-O-methyltransferase aTrm56, PAB1040 (gene)) is an enzyme with systematic name S-adenosyl-L-methionine:tRNA (cytidine56-2'-O)-methyltransferase. This enzyme catalyses the following chemical reaction S-adenosyl-L-methionine + cytidine56 in tRNA ⇌ {\displaystyle \rightleftharpoons } S-adenosyl-L-homocysteine + 2'-O-methylcytidine56 in tRNA T…

Key takeaways

TRNA (cytidine56-2'-O)-methyltransferase belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect TRNA (cytidine56-2'-O)-methyltransferase to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of TRNA (cytidine56-2'-O)-methyltransferase from memory before moving on to harder problems.

Reference excerpt

tRNA (cytidine56-2'-O)-methyltransferase (EC 2.1.1.206, aTrm56, tRNA ribose 2'-O-methyltransferase aTrm56, PAB1040 (gene)) is an enzyme with systematic name S-adenosyl-L-methionine:tRNA (cytidine56-2'-O)-methyltransferase. This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + cytidine56 in tRNA ⇌ {\displaystyle \rightleftharpoons } S-adenosyl-L-homocysteine + 2'-O-methylcytidine56 in tRNA The archaeal enzyme specifically catalyses the S-adenosyl-L-methionine dependent 2'-O-ribose methylation of cytidine at position 56 in tRNA transcripts.

Worked examples

Example 1 — a first encounter with TRNA (cytidine56-2'-O)-methyltransferase

Start with the simplest possible case. Write down what TRNA (cytidine56-2'-O)-methyltransferase claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to TRNA (cytidine56-2'-O)-methyltransferase before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about TRNA (cytidine56-2'-O)-methyltransferase ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of TRNA (cytidine56-2'-O)-methyltransferase

In research: TRNA (cytidine56-2'-O)-methyltransferase appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses TRNA (cytidine56-2'-O)-methyltransferase in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: TRNA (cytidine56-2'-O)-methyltransferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.1.1, Molecular biology stubs, so understanding it makes those chapters shorter.
In everyday life: Look for TRNA (cytidine56-2'-O)-methyltransferase outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
